Question

Select all of the factors that affect the rate of a chemical reaction:

a. Amount of enzyme
b. Substrate concentration
c. pH of the reaction environment
d. Temperature of the reaction environment

Answer 1

The factors that affect the rate of a chemical reaction include the amount of enzyme, substrate concentration, pH of the reaction environment, and temperature of the reaction environment.

Step-by-step explanation:

The factors that affect the rate of a chemical reaction are:

1. Amount of enzyme: The concentration of the enzyme can affect the reaction rate. Higher enzyme concentrations can generally increase the rate of the reaction.
2. Substrate concentration: The concentration of the substrate (the reactant) can also affect the reaction rate. Higher substrate concentrations can generally increase the rate of the reaction.
3. pH of the reaction environment: The pH level can influence the activity of the enzyme, and therefore affect the reaction rate.
4. Temperature of the reaction environment: Temperature can affect the rate of a chemical reaction. Increasing the temperature generally increases the reaction rate, up to a certain point.
