A chemical reaction occur at the same rate at 500K as at 300K" in presence of catalyst.If catalyst decreases the activation energy by "35kJ/mole , then calculate the activation energy of uncatalysed reaction (in kJ/mole)

The lowering of activation energy by catalyst is due to :

The rate of a catalysed reaction at 27^(@)C is e^(2) times the rate of uncatalysed reaction at 727^(@)C . If the catalyst decreased the activation energy by 6 Kcal/mol, the activation energy of uncatalysed reaction is (consider the same value of pre-exponential factors in both cases):
