At 27^@C in the presence of a catalyst, the activation energy of a reaction is lowered by 10 kJ mol^-1 . The ratio of log k (catalyst)/k (uncatalysed) is

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 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):
