What is the effect of temperature on rate of a reaction.

Arrhenius studies the effect of temperature on the rate of a reaction and postulated that rate constant varies with temperature exponentially as k=Ae^(-E_(a)//RT) . This method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied. If x is the fraction of molecules having energy greater than E_(a) it will be given by : a) x=-(E_(a))/(RT) b) In x=-(E_(a))/(RT) c) x=e^(E_(a)//RT) d) Any of these
