Fine Beautiful Order And Molecularity

Order is determined experimentally and molecularity is the sum of the stoichiometric coefficient of rate-determining elementary step.

Order and molecularity. Session watch this videohttpsyoutubeo7aLqtsRUQoCheck these playlists for video lecturesFor physics lectureshttps. The molecularity of a reaction represents the number of atoms molecules or ions that will interfere with each other for the chemical reaction to occur within a limited time frame. It is the sum of the exponents in the rate law equation.

It is an experimentally determined property. Two reactant molecules collide with one another in a bimolecular reaction. The molecularity of a reaction is the number of molecules reacting in an elementary step.

The rate of a reaction depends on concentration while the rate constant is affected by temperature and the presence of a catalyst. Hence Option E is the correct answer.

It is the number of atoms ions or molecules that must collide with one another. Difference between Order and Molecularity Order vs Molecularity 1. The order of reaction is an empirical quantity determined by experiment from the rate law of the reaction.

It is an experimental quantity. It is the sum of the powers to which the concentration terms are raised in the rate law equation. As discussed the molecularity of complex chemical reaction might not the stoichiometric sum.

It is a theoretical entity. Order and molecularity can be same only for elementary reaction and it is different for complex reaction. The main difference between the order of a reaction and molecularity of a reaction are given below.
