The Theory And Factors Affecting Reaction Rates

In reference to the collision theory, molecules act as small spheres that collide and bounce off each other, transferring energy among themselves when the collide. In order for a reaction to occur, there must be collisions between molecules. Through experimentation, factors are discovered that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, surface area, the physical state of reactants, and a catalyst. This experiment regarding the factors that affect reaction rate tests the effects of increased concentration and

Enzyme catalysis is dependant upon factors such as concentration of enzyme and substrate, temperature and pH. These factors determine the rate of reaction, and an increase in temperature or pH above the optimum will

Statement of Inquiry: What is the effect of changing a factor on the rate of chemical reaction?

Three factors that can affect the rate of reaction are temperature, pH and the salinity.

Question: How does changing enzyme concentration or temperature affect the reaction time of enzyme activity?

This image explains that the higher the temperature, the concentration, and the pressure the faster the rate of the reaction is.

As the substrate in increased the initial reaction rate will increase until it is fully submerged and then will not increase any more. The relationship is linear. As the substrate concentration increases, the initial reaction rate increases.

This occurs because as more hydrogen peroxide decomposes, there is less availability for catalase and hydrogen peroxide to form the enzyme-substrate complex, causing the rate of the reaction to decrease over

Science Coursework – What factors effect the rate of reaction between magnesium and hydrochloric acid? Background Knowledge There are four factors that can affect the rate of reaction and they all rely on the collision theory. This is basically how hard and how often particles collide with each other. The more and harder they collide, the faster the reaction time will be.

As an enzyme-catalyzed reaction may be the main reason for a reaction to occur faster, many factors can

The rate of decomposition due to catalase did not gradually increase at a constant rate because although the substrate concentration was increasing, it is unable to help increase the optimum activity of the enzyme. Although the number of substrate available for the enzyme is increasing,

Reactions will take place rapidly at much lower temperatures when

reaction rate increases. If the temperature of an enzyme gets to high the reaction rate will slow

Collision theory is the cause of all reactions between particles (atoms). For a reaction to occur the atoms have to collide with each other. Not just collide, but collide each other in the correct place and the correct orientation for the reaction to occur. These atoms then need to exceed activation energy; there are certain ways to increase all these. One of these ways is to increase the concentration of the solutions being reacted with each other because the higher the concentration, the higher the amount of atoms present therefore

This question is important to understand because Catalase plays a vital role in the sustenance of cells and tissues
