For a reaction \(A+B+30\text{ }kcal \rightarrow Product\) the energy of activation of its backward reaction is "50" kcal. The energy of activation of its forward reaction is

For a reversible reaction, A + B ? C + D , Delta H = – A kcal. If energy of activation for the forward reaction is B kcal, the energy of activation for backward reaction in kcal is :

The E_a for forward reaction is 50 kcal. The E_a for its backward reaction is:

Consider the reaction A to 2B + C, Delta H = -15 kcal . The energy of activation of backward reaction is 20 kcal mol^(-1) . In presence of catalyst, the energy of activation of forward reaction is 3 kcal mol^(-1) .At 400 K the catalystcauses the rate of the forward reaction to increase by the number of times equal to -

Given : AhArrB+C, DeltaH=-"10 kcals" , the energy of activation of backward reaction is "15 kcal mol"^(-1) . If the energy of activation of forward reaction in the presence of a catalyst is "3 kcal mol"^(-1) the catalyst will increase the rate of reaction at 300 K by the number of times equal to
