Question

The phenomenon when a reaction influences the rate of other reaction is ___.

1. homogenous catalysis
2. heterogeneous catalysis
3. induced catalysis
4. competitive catalysis

Answer 1

When one reaction influences the rate of other reaction, which does not occur under ordinary conditions, then this phenomenon is induced catalysis.

Example:

Sodium sulphite solution oxidises in the air but sodium arsenite solution does not oxidise by passing air.But when both solutions are mixed and the air is passed through the solution, then both the substances get oxidised.
