Kinetic energy is directly proportional to the absolute temperature and the number of molecules possessing higher energies increases with increase in temperature, i.e., most probable kinetic energy increases with increase in temperature.


Energy of activation is related to temperature by the following Arrhenius equation
$$
k=A e^{-E_a / R T}
$$
where $A$ is the Arrhenius factor also called pre-exponential factor.
$R$ is gas constant and $E_a$ is activation energy. Thus, it also shows an increase with rise in temperature.
