Write the difference between order and molecularity of reaction.
| Order | Molecularity |
| Order is a measure of the number of reactant species involved in a reaction. | Molecularity is a measure of the number of molecules involved in a reaction. |
| Order is determined by observation. | Molecularity is inferred from the reaction rate equation. |
| Order is independent of the reaction rate. | Molecularity is dependent on the reaction rate. |
| Order can be zero. | Molecularity cannot be zero. |
| Order is a descriptive term. | Molecularity is an inferential term. |
