320297 Statement A :
Catalyst changes the individual energies of the reactants and products.
Statement B :
Catalyst allows more number of molecules are able to cross the barrier per unit time.

320298 For the reaction, \({\mathrm{A \rightleftharpoons B, E_{a}=50 \mathrm{~kJ} \mathrm{~mol}^{-1}}}\) and \({\mathrm{\Delta \mathrm{H}=-20 \mathrm{~kJ} \mathrm{~mol}^{-1}}}\). When a catalyst is added, \({\mathrm{\mathrm{E}_{\mathrm{a}}}}\) decreases by \({\mathrm{10 \mathrm{~kJ} \mathrm{~mol}^{-1}}}\). What is the for the backward reaction in the presence of catalyst?

320299 The energy of activation of positive catalyzed reaction as compared to that of an uncatalyzed reaction is

320300 Assertion :
The addition of catalyst lowers the activation barrier, yet there is no change in the enthalpy.
Reason :
Enthalpy change is equal to the differenee in the activation energy for the forward and the backward reaction.

320301 The variation of the rate of an enzyme catalyzed reaction with substrate concentration is correctly represented by graph

320297 Statement A :
Catalyst changes the individual energies of the reactants and products.
