Question

part 2 of 2 what effect would decreasing the temperature have on the reaction rate? select the single best answer. reaction rate increases. reaction rate decreases. reaction rate stays the same.

Explanation:

Reaction rate is related to the kinetic energy of particles. Lowering temperature reduces particle kinetic energy, so they collide less frequently and with less energy, decreasing the reaction rate.

Answer:

B. Reaction rate decreases.
