Define the order of reaction. Give one example for fraction order reaction.

Answer»

Solution :The SUM of the powers of the concentration terms of each reactant in the experimentally determined rate EQUATION is called order of reaction.
Example for fractional order reaction is
`H_(2) + Br_(2)rarr 2HBR`
Rate eqn is `r = K[H_(2)]^(1)[Br_(2)]^((1)/(2))`
order = 1+0.5= 1.5
