Chemical Kinetics · Arrhenius equation

Correct statements regarding Arrhenius equation among the following are :
  • (A)Factor e−Ea/RT\mathrm{e}^{-\mathrm{Ea}/\mathrm{RT}} 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∘^\circC doubles the rate of reaction.
  • (D)Plot of log k vs 1T\dfrac{1}{\mathrm{T}} gives a straight line with slope =−EaR= -\dfrac{\mathrm{Ea}}{\mathrm{R}}.
