#### Answer

a) $T_2$ is greater than $T_1$. b) As temperature increases, the reaction rate increases.

#### Work Step by Step

a) The average collision energy of the reactants at $T_2$ is greater than that at $T_1$; therefore, $T_2$ must be at a higher temperature than $T_1$. b) As temperature increases, the probability that the collision of the reactants will have enough energy to overcome the activation energy of the reaction increases; therefore, more of the collisions result in reactions, and the reaction rate increases.
