The rate of a reaction quadruples when the temperature changes from 293 K to 313 K. Calculate the energy of activation of the reaction assuming that it does not change with temperature.


Given, k2 = 4k1, T1 = 293K and T2 = 313K


We know, From Arrhenius equation, we obtain





On solving we get,


Ea = 58263.33 J mol-1 or 58.26 kJ mol-1
