The rate of a reaction may be increased by ________.

Question

Quizplus · Accepted Answer

All of the choices listed (increasing the concentration of reactants, increasing the temperature, and adding a catalyst) are ways to increase the rate of a reaction. Increasing the concentration of reactants means there are more molecules available to react, which can increase the frequency of collisions between particles. Increasing the temperature increases the kinetic energy of particles, which can also increase the frequency of collisions and the likelihood that they will have enough energy to react. Adding a catalyst provides an alternative pathway with lower activation energy, making it easier for the reaction to occur at a faster rate.
