Question

Assertion (A): Activation energy for the acid catalysed hydrolysis of sucrose is

6.22 \mathrm{~kJ} \mathrm{~mol}^{-1}

, while the activation energy is only

2.15 \mathrm{~kJ} \mathrm{~mol}^{-1}

. When hydrolysis is catalysed by the enzyme sucrose.

Reason (R): Enzymes the biocatalysts, reduce the magnitude of activation energy by providing the alternative path. In the hydrolysis of sucrose the enzyme sucrose reduces the activation energy from

6.22 \mathrm{~kJ} \mathrm{~mol}^{-1}

to

2.15 \mathrm{~kJ} \mathrm{~mol}^{-1}

.
