Why can we not determine the order of a rection by taking into consideration the balanced chemical equation ?

Text Solution

Verified by Experts

The rate of reaction may not depend upon all the molecules of a reactant present in the balanced chemical equation. It has to be determined experimentally that on what power of molar concentration of that reactant, the rate depends. Summing up the powers of molar concentrations of different reactants as determined experimentally gives the overall the overall order of reaction.
