The Kinetics of the Decomposition of Dinitrogen Pentaoxide Is Studied $\degree$

The kinetics of the decomposition of dinitrogen pentaoxide is studied at 50 $\degree$ C and at 75 $\degree$ C. Which of the following statements concerning the studies is correct?

A) The rate at 75 $\degree$ C will be greater than the rate at 50 $\degree$ C because the activation energy will be lower at 75 $\degree$ C than at 50 $\degree$ C.
B) The rate at 75 $\degree$ C will be greater than the rate at 50 $\degree$ C because the activation energy will be higher at 75 $\degree$ C than at 50 $\degree$ C.
C) The rate at 75 $\degree$ C will be less than the rate at 50 $\degree$ C because the molecules at higher speeds do not interact as well as those at lower speeds.
D) The rate at 75 $\degree$ C will be greater than at 50 $\degree$ C because the concentration of a gas increases with increasing temperature.
E) The rate at 75 $\degree$ C will be greater than the rate at 50 $\degree$ C because the number of molecules with enough energy to react increases with increasing temperature.
