What are the differences between order and molecularity ?

Differences between order and molecularity: Order No. Molecularity It is the sum of powers of the concentrations in the rate law expressions. 01 It is the number of molecular of reactants taking part in an elementary reaction or in a rate determining step of a complex reaction. Order corresponds to the overall reaction. 02 Molecularity … Read more
