Based on the previous results, the hypothesis was confirmed. These data also agree with the theory stating that the larger the surface area of a reactant, the faster the reaction. A larger surface area indicates that a bigger quantity of particles are brought into contact with the other reactant, this increases the probability of collisions between the particles leading to a faster
The increase in collisions between the substrate molecules is due to the increase in rate. Usually the rate of enzyme catalyzed reaction doubles for every ten degree rise in temperature. Increase in temperature beyond optimum level causes a sharp decline in the rate due to denaturation of the enzyme. At around 40 degrees Celsius most enzymes have an optimum temperature and when temperatures are reduced below freezing point enzymes are inactivated but they gain their catalytic properties once the temperature is increased. Figure: (www.bbc.co.uk) 2. pH – Enzymes function most effectively over a particular pH range which is quite often a narrow range.
Collisions increase or become more violent between molecules at higher temperatures or decrease as the temperature is lowered. Some factors that influence the speed of a chemical reaction are: (1) surface area of starting reactants; (2) concentration of reactants; (3) temperatures. The particle theory states that a solute dissolved takes place at the surface of the solvent and the larger the surface area of the particle the longer it will take to dissolve. The smaller the area the faster it will
This does not occur with every collision, so certain methods are used to increase the probability of a successful collision, and thus increasing the rate of reaction. One of these methods is increasing the concentrations of the reactants. Increased concentrations results in particles colliding more frequently, and more successful collisions will occur. On a graph, there would be a decreasing curve as the concentrations of reactants decreases as the reaction
Hypertrophy refers to an increase in the size of the skeletal muscle. Furthermore, there are two different categories of hypertrophy; Transient and Chronic. Transient hypertrophy is a more immediate effect following a single bout of exercise. It is caused by fluid accumulation in the muscle space. However, chronic hypertrophy refers to more long-term changes in the muscle.
The economic logic behind protectionist immigration agendas is that an increased population increases the labor supply and stops there. In this scenario, the equilibrium wage rate of labor supply and labor demand would be lower than the pre-immigration equilibrium wage rate, and the logic holds. Instead, separating scenario from real-world application would present previously unaccounted for effects. Being so, what actually occurs is as follows. As before, as the population increases with immigration, the labor supply would also increase, but the increased population would also lead to increased consumer spending and demand (i.e.
With higher production costs and productivity at it maximum, companies cannot maintain profits by producing the same amounts of goods and services. As a consequence, the increased costs are passed on to customers, causing a rise in the overall price level (inflation). Demand-pull inflation occurs when there is an increase in collective demand, categorized by the four sections of the macro economy: governments, households, businesses and foreign buyers. When these four sectors at the same time want to purchase more output than suppliers can produce, buyers compete to acquire limited amounts of goods and services. Buyers then bid prices up, again and again, causing inflation.
The faster an bject moves the more kinetic energy it has. The kinetic energy increases as its mass increases. Potential energy is stored energy, which means that an object can have energy even if it is not in motion. Some other forms of this energy include gravitational potential energy, elastic potential energy, and chemical potential energy. Friction is the force that resists the motion of two surfaces sliding against one each other.
Cost-push inflation happens when we face higher prices due to the increase in cost of production and higher costs of raw materials. It is determined by supply side factors. Cost-push inflation can be caused by higher price of commodities, imported inflation, higher wages, higher taxes and higher food prices (Economics Help, 2011). Demand-pull inflation happens when there is an increase in the price of goods and services when demand increases too much that it outpaces supply (US Economy, 2015). Sometimes people refer it as “too much money chasing too few goods”.
