Arrhenius studied the effect of temperature on the rate of a reaction and postulated that rate constant varies with temperature exponentially as k=Ae−EaRT
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 Ea
it will be given by:
- Any of these
- ln x=−EaRT
