Which of the following factors will influence the rate of chemical reactions?

Question

Quizplus · Accepted Answer

All of these factors, temperature, concentration of reactants, presence of catalysts, and presence of enzymes, will influence the rate of chemical reactions. Temperature can increase the kinetic energy of molecules, making them collide more frequently and with more force, leading to an increased reaction rate. Increasing the concentration of reactants increases the likelihood of reactant molecules coming into contact with each other, also leading to an increased reaction rate. Catalysts are substances that can speed up a reaction without being used up themselves, by decreasing the activation energy required for the reaction to occur. Enzymes are biological catalysts that specifically increase the rate of biochemical reactions in living organisms.
