Question

distingush between order and molecularity​

Answer 1

Order;

• order of reaction as the number of molecules of the reactant whose concentration changes during the chemical change.

• Order of reaction is calculated by experiment from rate law of reaction.

Molecularity;

• Molecularity is the number of ions or molecules that take part in the rate-determining step.

Answer 2

Answer:

We define order of reaction as the number of molecules of the reactant whose concentration changes during the chemical change. Molecularity is the number of ions or molecules that take part in the rate-determining step. ... Order of reaction is calculated by experiment from rate law of reaction.
