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

E. Amount of enzymes

F. pH of the reaction environment

G. Temperature of the reaction environment

Answer 1

The factors that affect the rate of reaction are;

• Amount of enzyme
• Substrate concentration
• pH of the reaction environment
• Temperature of the reaction environment

Rate of chemical reaction

The rate of a chemical reaction is influenced by four main factors: pH, temperature, concentration, and enzymes. Temperature causes reactant collisions to occur more frequently and with greater energy, which speeds up reactions.

An increase in substrate concentration speeds up the reaction by increasing the likelihood of a collision. By decreasing the activation energy and accelerating the reaction, enzymes function as catalysts. Finally, appropriate enzyme activity and a conducive environment for the reaction to proceed are guaranteed by an ideal pH.
