Correct statements regarding Arrhenius equation among the following are :
A. Factor $\displaystyle e^{-E a / R T}$ corresponds to fraction of molecules having kinetic energy less than Ea.
B. At a given temperature, lower the Ea, faster is the reaction.
C. Increase in temperature by about $\displaystyle 10$°C doubles the rate of reaction.
D. Plot of log k vs $\displaystyle \frac{1}{\mathrm{~T}}$ gives a straight line with slope = $\displaystyle -\frac{\mathrm{Ea}}{\mathrm{R}}$.
