Chemical equilibrium Essays

Ksp is known as an equilibrium constant of the solubility product, but Kc is used for the equilibrium constant of the reaction. Ksp is a representation of the level at which a soluble solution can dissolve. The greater the solubility of a substance, the higher the Ksp. The constant of the value Ksp tells the

gained or released) of various state changes, such as chemical reactions. Calorimetry can also be used in a number of other ways, however, including in microbiology (where the presence of various microorganisms can be determined as their multiplication increases thermal power) and in environmental science (where a calorimeter can be used to determine insect metabolism as it varies based on changes in such factors as temperature and chemical treatments)1. There are numerous kinds of calorimeters

To find chemical equilibrium, the following chemical equation is used in the experiment: Fe3+(aq) + SCN-(aq)  FeSCN2+(aq). When iron (III) and thiocyanate react, thiocyanoiron (III) is produced. When the concentration of all ions at equilibrium are known, the equilibrium constant can be calculated by dividing the equilibrium concentration of the reactant by the equilibrium concentration of the products. In this experiment, four equilibrium systems containing different concentrations of three different

Experiment 2: Preparation and Spectrophotometric Analysis of Copper(I) Iodide Abstract: This experiment aims to determine the concentration of “Purified CuI” sample. Crude CuI is obtained by reacting CuSO4.5H2O with KI and Na2S2O3 in de-ionized water. A series of decanting and centrifugation is carried out to extract the crude CuI. Crude CuI was later purified by dissolving it in hot KI solution. The solution was later transferred into de-ionized water and placed in an ice bath to allow for re-precipitation

proteins in nature. They catalyze or accelerate the chemical reactions. They speed up the chemical reactions by providing an alternative reaction pathway of lower activation energy. The molecules on which enzymes acts are called substrates and these are converted into different molecules called products. All the metabolic processes in the cell need enzymes to occur at a faster rate to sustain life. Like all other catalysts, enzymes take part in the chemical reactions - that is how they provide an alternative

energy necessary to do chemical reactions within the body”. They are considered biological catalyst. When the environment changes, the ability of an enzyme to catalyze a reaction decreases. Very high temperatures can denature enzymes by destroying their bonds and their shapes. Low temperatures, can cause enzymes to slow down and decrease their rate of interaction with substrates. The structure of an enzyme are chains of amino acids, and have a specific shape that allow chemicals to react with the enzyme

formation of these new bonds results in the formation of the product by measuring the changes in absorbance due to the substrate (starch) being changed into product by the amylase enzyme. Since the starch and buffer used in the experiment contain chemicals

Introduction: Enzymes are proteins that function as catalysts, meaning that they increase the speed of a reaction without being changed themselves. The enzyme has two main jobs in a reaction that cause the reaction to increase. The first job is to bring substrates (the substances that the enzyme will be reacting on that bind to the active site in the beginning a reaction) together in an orderly fashion so that they can interact during the reaction. It’s second job is to decrease the energy needed

An enzyme is a biological catalyst (protein) which speeds up the rate of chemical reactions without changing the chemical reaction at the end. A chemical reaction is when a substance is changed into a different substance. To begin a reaction, you need energy which in this case is called activation energy. A reaction in a chemical reaction is called a substrate when it is being acted upon by an enzyme that speeds up the rate of a reaction. In addition, the region on the enzyme where the substrate

Enzymes are essential in the body because without them, the chemical reactions would take place too slowly and we would die as a result. Depending on the type of enzyme will depend on its job. Enzymes also help with cell growth and communication, by keeping these under control. BACE1 is an enzyme that is found in

oneway reaction, however a reversible reaction will eventually reach a point of equilibrium where the products are reactant are produced at the same rate. ( AS and A level Chemistry book) Dynamic equilibrium occurs in a closed system where the amounts of products and reactants are not changing anymore and even though there is no visible change the chemical reaction is continually happening known term being equilibrium, where both forwards and backwards reactions are produced at the same rate. The

Abstract This assignment focuses on how deviance forms a part of major social institutions in our society i.e., religion, education, government, economy and family. It attempts to explore so, through different perspectives and live examples/ situations persisting in the India society. I have also tried to give examples of situations that I have witnessed in the agency I am placed, Crime against Women (CAW) Cell. What is Deviance? Though there is no exact or approved definition of Deviance but the

Throughout history, dating back to 3600 BC, games of chance and gambling have existed ("Introduction- Gambling and Probability"). Since their invention, people have tried to decipher ways to predict the outcome of such games, thus a need to determine the likelihood of winning in games such as these evolved. The method created to suit this need is known as probability theory. Probability theory has been developed over hundreds of years, and is used to predict possible outcomes and assist in daily

interaction of the Allies and the Axis during WWII. Finally, some of the crucial developments of game theory were brought by the work of the late John Nash, who in his 1950 treatise on non-cooperative games introduced a concept of equilibrium which we now know as the Nash equilibrium . Before we

The origins of the Poverty measure While studying the impact of minimum wage increases on poverty, it is of significant importance to understand how poverty is measured. According to the definition of poverty – “The U.S. Census Bureau determines poverty status by comparing pre-tax cash income against a threshold that is set at three times the cost of a minimum food diet in 1963, updated annually for inflation using the Consumer Price Index (CPI; see the last section of this FAQ for an explanation

Game Theory and the Prisoners’ Dilemma Strategic Rationality In this chapter, Daniel Little indicates that under circumstances of uncertainty and risks, decision-makers attempt to maximize utility through collecting information of the utility and analyzing the probability of each feasible choice. Finally the maximum expected payoff of outcomes is given to the decision-maker since all other decision makers also made the rational decisions. Also strategic rationality is embodied on interactive social

Essay #2 Progressing through life, view the twist and turns on the path that must be followed. Why must these obstacles be placed where they are and what makes it different from a perfectly straight path? Playing a board game is just the same as the journey of life. It wouldn’t be the same if all of it was just one simple path. There would be no point of playing. There would be no way to challenge yourself and make it competitive. It would be nearly impossible to learn anything from it. Just as without

9) Game Theory : It is a technique to deal with uncertainty situations related to management decisions such as bidding for tenders. 10) Goal Programming : It is a technique to convert multiple objectives into a simple goal. 11) Simulation : It is a technique to deal with probabilistic situation where mathematical models fail to provide solutions to real problems. 12) Scheduling : It is the process of preparing calendar for executing a set of jobs. 13) Non-linear programming : It is an extended version

I. Introduction The main aim of this paper is to introduce the gender differences that occur because of certain welfare state policies. The focus will be on three types of regimes: liberal, social-democratic, and conservative-corporatist; and how these three regimes incorporate the gender differences in their social policies. Welfare state policies, or social provisions began during the 1880s making this period known as the “formative period of the welfare state”. The policies were meant to improve
