Question

Difference between order and molecularity differences

Answer 1

Answer:

Difference between Order and Molecularity. (i) Order is an experimental property while molecularity is the theoretical property. (ii) Order concerns with kinetics (rate-law) while molecularity concerns with mechanism. ... (iv) Order may change with change in experimental condition while molecularity can't.

Answer 2

The number of ions or molecules that take part in the rate-determining step is known as molecularity. The sum of powers to which the reactant concentrations are raised in the rate law equation is known as the order of the reaction.
