Which of the following would increase the rate of chemical reactions? a. Increase in the amount of substrates
b. Increase in temperature
c. Decrease in amount of enzymes
d. Increase in the particle size of the substrates

B. Increase in temperature

Explanation:

An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision

answer : haversian
