Le Chatelier’s principle says that if you disturb a system in equilibrium the equilibrium will shift in order to account for the disturbance. In our experiment, we used excess acetic acid. The presence of excess acetic acid caused the reaction to shift toward the opposite side of the reaction. This resulted in the production of isopentyl acetate being favored, which allowed
Environmental Factors’ Effect on the Speed of Chemical Reactions Hypothesis: pH 8 solution will produce more oxygen during the chemical reaction than pH 3 because pH 8 is more basic and therefore would not denature the enzyme. Background information: The main function of all enzyme proteins is to act as a catalyst, speed up the chemical reaction and provide a place for it. The enzymes interact with specific substrates by combining at the active site of the enzyme. After this occurs the substrate detaches and leaves the active site as products, so the enzyme can become reusable to start the cycle all over again. The products of the chemical reaction are
Egocentrically, yes there is no doubt that the human extremes aren’t for the average person and what some people can physically and mentally do is impressive, but on a bigger scale, our extremes are not that extreme. We have to use tools outside of ourselves to achieve most of these extremes. The human version of extreme pales in comparison to some of the extremes other organisms encounter and even thrive in. Extremophiles, organisms who call the most extreme environments on earth home, would laugh at our version of going to the extreme. From the depths of the ocean to the peaks of mountains, where extreme is a “norm”, you can find organisms “comfortable” in their homes, breaking the human scale of extreme, and they do all of this with internal “tools”.
How the body responds to exercise: Musculoskeletal system- This system responds to acute exercise in the three following ways; There is an increase of blood supply during exercise and for a short amount of time afterwards. This therefore causes our body temperature to increase as well as metabolic activity in the muscles. The blood supply is increased due to the increase of metabolic activity as this increases the body’s demand for oxygen. This would apply in sports such as football as a footballers body would have to produce more red blood cells in order to allow more oxygen to be transported around the body and to the muscles in use so that the player can continue on for longer in matches. Muscle Pliability and range of movement is increased.
It is the only part of glucose metabolism that needs oxygen. There are electrons in the membrane of the mitochondria in the eukaryotic cells that are passed rapidly from one part to the next, then to endpoint where electrons reduce the oxygen to produce
Conclusion It was clearly observed that the decrease in the concentration of hydrogen peroxide lead to increase in the reaction time and also decrease in the rate of the reaction. Also the decrease on the concentration decreases the rate of the reaction. The two graphs were straight line graphs with positive slopes. So effective collision for a chemical reaction depends directly on the concentration of the reagent, that is, the crowdedness of the reacting molecules which increases reaction time and vice versa.

As the pH increases or decreases the concentration of hydrogen and hydroxide ions in the solution are altered. These ions alter the shape of the enzyme diminishing the ability for hydrogen peroxide to bind with the active sight of the catalase enzyme in turn decreasing
If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive and denatured. Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate cannot bind to the active site or it cannot undergo catalysis. Several factors are influenced directly by the pH in which the reaction takes place. Extremely high or low pH values generally result in complete loss of activity for most enzymes.
So far, conventional solutions to global warming — new government policies and changes in individual behaviour — haven't delivered. And more radical options, such as pumping sulphur into the atmosphere to counteract warming, pose a great deal of risk. There may be another route to avoid the potentially disastrous effects of climate change: We can deliberately alter ourselves, three researchers suggest. Human engineering, as they call it, poses less danger than altering our planet through geo-engineering, and it could augment changes to personal behaviour or policies to mitigate climate change, they write in an article to be published in the journal Ethics, Policy and the Environment.
