G Choose the best fit. Only choose one option once. A(n) is one for which the rate law can be written from the molecularity, i. e., from coefficients in the balanced equation. Answer 1 The is the number of species that must collide to produce the reaction represented by an elementary step in a reaction mechanism. Answer 2 The of a reaction is the series of proposed elementary reactions that may occur to give the overall reaction. The sum of all the steps in the gives the balanced chemical reaction.

A)An elementary step reaction

B) Molecularity

C) Mechanism of reaction

D.)Balance chemical equation

Explanation:

Molecularity is the number of molecules that react in an elementary reaction which is equal to the sum of stoichiometric coefficients of all reactants that participate in the elementary reaction.The reaction can be unimolecular or bimolecular depending on the number of molecules.

Mechanism of reaction reffered to the step by step sequence of elementary reactions through which the overall chemical reaction change occurs. It gives detail of the reaction in each stage of an overall chemical reaction.

An elementary step reaction reffered to is one step of reaction among the series of simple reactions that show how reaction is progressing at the molecular level.

c most likely

hop this let me know if it is wrong
