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)

Rate of reaction in absence of catalyst at 700 K is same as in presence of catalyst at 500 K. If catalyst decreases activation energy barrier by 30 kJ/mole, determine activation energy in presence of catalyst. (Assume 'A' factor to be same in both cases)

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):

(A) A catalyst increases the rate of areaction. (R)In presence of a catalyst, the activation energy of the reaction increases.

A hydrogenation reaction is carried out at 500 K . If the same reaction is carried out in the presence of a catalyst at the same rate, the temperature required is 400 K . Calculate the activation energy of the reaction if the catalyst lowers the activation barrier by 20 kJ mol^(-1) .
