Solution

The correct options are
A At lower temperature increase in temperature causes more change in the value of k.
B Rate of reaction $\propto 1 / E_{a}$
As we know,
$k = A e^{- E_{a} / R T}$
Rate constant depends upon the temperature only.
Also,
Lower is the activation energy, higher the rate of reaction.
