What are zero order reactions ? Give example.

Text Solution

Verified by Experts

These are the reactions in which the rate of reaction is independent of the concentration of the reactants. Such reactions are called zero order reactions.
For example : `H _(2) (g) + Cl _(2) (g) overset( hv) to 2HCl (g)`
According to rate law, Rate `= k [ H _(2)]^(0) [Cl _(2) ] ^(0) therefore ` Order of reaction =0.
