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:

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 3 kcal at 27^@C . Hence, the rate of reaction will increase by:

In the presence of a catalyst, the activation energy is lowered by 3 Kcal at 27^(@) c .Hence the rate of reaction will increase by :

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 : -
