Some other examples are given below:
Reaction
Experimental rate expression
1 CHCl3 + Cl2 ®  CCl4 + HCl
Rate = k [CHCl3 ]  [Cl2]1/2
2 CH3COOC2H5 + H2O ®  CH3COOH + C2H5OH Rate = k [CH3COOC2H5]1 [H2O]0
In these reactions, the exponents of the concentration terms are not
the same as their stoichiometric coefficients Thus, we can say that:
Rate law for any reaction cannot be predicted by merely looking at
the balanced chemical equation, i
