JEE MainChemistryChemical Kinetics and Nuclear ChemistryNumerical+4 / −1
For a reversible reaction A⇌B\mathrm{A} \rightleftharpoons \mathrm{B}A⇌B, the ΔHforward reaction=20 kJ mol−1\Delta \mathrm{H}_{\text{forward reaction}} = 20 \mathrm{~kJ} \mathrm{~mol}^{-1}ΔHforward reaction​=20 kJ mol−1. The activation energy of the uncatalysed forward reaction is 300 kJ mol−1300 \mathrm{~kJ} \mathrm{~mol}^{-1}300 kJ mol−1. When the reaction is catalysed keeping the reactant concentration same, the rate of the catalysed forward reaction at 27∘C27^{\circ} \mathrm{C}27∘C is found to be same as that of the uncatalysed reaction at 327∘C327^{\circ} \mathrm{C}327∘C. The activation energy of the catalysed backward reaction is ‾kJ mol−1\underline{\hspace{2cm}}\mathrm{kJ}~ \mathrm{mol}^{-1}​kJ mol−1.
