The energy of activation for a reaction is `100 KJ mol^(-1)`. The peresence of a catalyst lowers the energy of activation by `75%`. What will be the effect on the rate of reaction at `20^(@)C`, other things being equal?

The energy of activation for a reaction is 100 (kJ) mol^(-1) . Presence of a catalyst lowers the energy of activation by 75 %. What will be the effect on the rate of reaction at (20^oC) , other things being equal.

The energy of activation for a reaction is 50kJ/ mol. Presence of a catalyst lowers the energy of activation by 25%. What will be the effect on rate of reaction at 30^(@) C- Other things remains same.

The energy of activation for a reaction is 100 kJ/mol. Presence of a catalyst lowers the energy of activation by 75%. The ratio of k_(cat)//K_(uncat) at (T=298K) is :

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 )

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 )

A catalyst lowers the activation energy for a certain reaction from 75 kJ to 25" kJ mol"^(–1) . What will be the effect on the rate of reaction at 25^(@)C , after things being equal.

The energy of activation for a reaction is 100 kJ/mol at 57^(@)C . Presence of catalyst lower activation energy by 25%. The rate of reaction is increased by 10^(x) the value of x is

With 100 kJ mol- activation energy for an uncatalysed reaction at 20°C, the catalyst lowers the energy of activation by 75%. What will be the effective rate if other conditions are same?
