Dependence of Rate on Concentration
CHXII04:CHEMICAL KINETICS

320171 Assertion :
In rate law, unlike in the expression for equilibrium constants, the exponents for concentrations do not necessarily match the stoichiometric coefficients.
Reason :
It is the mechanism and not the balanced chemical equation for the overall change that governs the reaction rate.
