A catalyst lowers the activation energy of a reaction form 20 kJ mol^(-1) to 10 kJ mol^(-1) . The temperature at which the uncatalyzed reaction will have the same rate as that of the catalyzed at 27^(@)C is

A catalyst lowers the activation energy of a reaction form 20 kJ mol^(-1) to kJ mol^(-1) . The temperature at which the uncatalyzed reaction will have the same rate as that of the catalyzed at 27^(@)C is

A catalyst lowered the energy of activation by 25 kJ mol^(-1) .How many times , the rate reaction increases?

A catalyst lower the activation energy of a reaction from 200KJ "mol"^(-1) to 100 KJ "mol"^(-1) . The temperature at which the rate of uncatalysed reaction will be same as the rate of catalysed reaction at 25^(@)C is (assuming Arrheneous consant A to be same in both the case)

A catalyst lowers the activation energy of a reaction from 20 kJ mol^(-1) to 10 kJ mol^(-1). The temperature at which uncatalysed reaction will have same rate as that of catalysed at 27°C is

The temperature at which the catalystic activity of the catalysts is maximum ,is called

The energy of activation for ab uncatalysed reaction is 100KJ mol ^(-1) presence of a catalyst lowers the energy of activation by 75% . The log _(10).K_2/K_1 of the ratio of rate constant of catalysed and uncatalysed reactions at 27^@C is ? Assume the frequency factor is same for both reactions. ( Given 2.303xx8.314 = 19.147 )
