Correct statements regarding Arrhenius equation among the following are.
A. Factor $e^{-E a / R T}$ 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 $10^{\circ} \mathrm{C}$ doubles the rate of reaction.
D. Plot of $\log \mathrm{k}$ vs $\frac{1}{\mathrm{~T}}$ gives a straight line with slope $=-\frac{\mathrm{Ea}}{\mathrm{R}}$.
