Question

Quizplus · Accepted Answer

All of these factors—temperature, concentration of reactants, presence of catalysts, and presence of enzymes—affect the rate of chemical reactions. Temperature can increase reaction rates by providing more kinetic energy to the reactants. Higher concentrations of reactants increase the likelihood of collisions between reactant molecules, thus increasing the rate. Catalysts and enzymes lower the activation energy required for a reaction, also speeding up the process.
