Question

Identify which property changes as temperature increases to increase the reaction rate.

A) Increasing the temperature decreases the molecular motion.
B) Increasing the temperature reduces the collision frequency.
C) Increasing the temperature divides the solubility of the solute.
D) Increasing the temperature increases the energy of the molecules.

Answer 1

D) Increasing the temperature increases the energy of the molecules.

Step-by-step explanation:

Increasing the temperature increases the energy of the molecules.

As temperature increases the energy of the molecules increases and the energy of the collision making it more likely for a reaction to occur.

Answer 2

Answer:D

Explanation:according to Kinetic molecular theory the kinetic energy is directly proportional to the absolute temperature.

It means that when we increase the temprature the motion of molecules increase,as a result the rate of reaction is also increased.

Which means that the effective collision is also increased.
