Question

Give example(s) of the following : Reaction whose order of reaction is fractional.

Answer 1

In fractional order reactions, the orderis a non-integer, which often indicates a chemical chain reaction or other complex reaction mechanism. Forexample, the pyrolysis of acetaldehyde (CH3CHO) into methane and carbon monoxide proceeds with an order of 1.5 with respect to acetaldehyde: r = k[CH3CHO]3/2.
