Which of the following changes will increase the reaction rate?

Question

Quizplus · Accepted Answer

Increasing the concentration of reactants will increase the number of collisions between the reactants and increase the likelihood of successful collisions, leading to an increase in the reaction rate. Option A is incorrect because increasing the concentration of products would actually shift the equilibrium in the reverse direction, slowing down the reaction rate. Option B is also incorrect as reducing the temperature will decrease the kinetic energy and reduce the number of collisions between the reactants, thus lowering the reaction rate. Option C is incorrect because allowing more time for the reaction to occur will not change the frequency of collisions or the likelihood of successful collisions, and therefore will not increase the reaction rate.
