An elementary reaction is a chemical reaction in which one or more chemical species react directly to form products in a single reaction step and with a single transition state.

## What is elementary reaction example?

An elementary reaction is a reaction that occurs in a single step. The rate law for an elementary reaction can be derived from the coefficients of the reactants in the balanced equation. For example, the rate law for the elementary reaction 2A + B → products is rate = k[A]²[B].

## What is an elementary process?

An elementary process is also called an elementary step or elementary reaction. It expresses how molecules or ions actually react with each other. The equation in an elementary step represents the reaction at the molecular level, not the overall reaction. A bimolecular process involves two reacting molecules or ions.

## What is a non elementary reaction?

Representation of a non elementary reaction : A non-elementary reaction is the one whose stoichiometry does not match with its kinetics(i.e., for such a reaction there is no direct correspondence between reaction order and stoichiometry).

## How do you determine which step is the rate determining step?

The reaction mechanism is the step-by-step process by which reactants actually become products. The overall reaction rate depends almost entirely on the rate of the slowest step. If the first step is the slowest, and the entire reaction must wait for it, then it is the rate-determining step.

## What is the rate determining step in an energy diagram?

Rate determining step (rds; rate limiting step): The mechanism step with the greatest activation energy (i.e., the slowest step) and therefore the step that has the greatest influence on reaction rate.

## What is an energy diagram?

An energy diagram can be defined as a diagram showing the relative potential energies of reactants, transition states, and products as a reaction progresses with time.
