The rate constant of a reaction may be increased by ________.

Question

Quizplus · Accepted Answer

All of the listed options can increase the rate constant of a reaction. Increasing the concentration of reactants increases the frequency of collisions between particles, thereby increasing the likelihood of reaction. Increasing the temperature provides more energy to the particles, allowing them to overcome activation energy barriers more easily. Adding a catalyst provides an alternative pathway for the reaction with a lower activation energy, allowing the reaction to proceed more quickly.
