How does increasing the temperature of a reaction affect the reaction rate?
A) It slows the rate down by changing the heat of reaction.
B) It speeds the rate up by raising the activation energy.
C) It slows the rate down by increasing the activation energy.
D) It speeds the rate up by increasing the kinetic energy of the molecules.
E) It slows the rate down by increasing the kinetic energy of the molecules.

Question

Quizplus · Accepted Answer

Increasing the temperature of a reaction increases the kinetic energy of the molecules involved. This increase in kinetic energy means that more molecules have the energy needed to overcome the activation energy barrier, leading to an increase in the reaction rate.
