In the presence of catalyst, the activation energy of the reaction is lowered by 2 kcal at 27^(@)C . The rate of reaction will increased by

In presence of a catalyst, the activation energy is lowered by "2" kcal at \(127^{o}\)C .Hence, the rate as compared to the old rate is \(e^{x}\) times. then the value of "x" is

For a given reaction, presence of catalyst reduces the energy of activation by 2 kcal at 27^(@)C . Thus rate of reaction will be increased by:

The activation energy of a first order reaction at 300 K is kJ mol^(-1) . In the presence of a catalyst, the activation energy gets lowered to 50kJ mol^(-1) at 300 K . How many times the reaction rate change in the presence of a catalyst at the same temperature ?

At 227^(@)C , the presence of catalyst causes the activation energy of a reaction to decrease by 4.606 K cal. The rate of the reaction will be increased by : -
