Activation energy for the acied catalysed hydrolysis of sucrose is 6.22 KJ mol ^(-1), while the activation energy is only 2.15 KJ mol^(-1) when hydrolysis is catalysed by the enzyme sucrose. Explain. |
| Answer» Solution :Enzymes are biocatalysts. They reudce the MAGNITUDE of activation energy by providing ALTERNATIVE path. For example, in the hydrolysis of sucrose , the enzyme sucrase reduces the activation energy from `6.22 kj mol^(-1)` to `2.15kj mol^(-1)`. As a result , enzyme catalysed REACTIONS occur at a MUCH faster rate than the ordinary LABORATORY chemical reactions using conventional catalysts. | |
