To be effective, however, the chemical reaction must meet three necessary conditions: the reaction must not occur too quickly or too slowly; we must know the reaction’s rate law; and we must be able to monitor the change in concentration for at least one species.

It provides a general formula for calculating reaction rates using concentration changes of reactants and products. An example illustrates these concepts, demonstrating how to calculate the time-rate of change for concentrations in a reaction between nitrogen and hydrogen forming ammonia.

Experimentally determined rate law expressions show how the rate of a reaction depends upon the concentrations of the reactants and sometimes the products, too. This knowledge can be used to gain insight into the detailed molecular pathway (the mechanism) by which the reaction occurs. Understanding the mechanism allows chemists to devise ways of optimizing chemical reactions.

It h...This page discusses the Lindemann mechanism, which outlines reactions via elementary steps and the role of activated intermediates, leading to variable reaction orders under different conditions. It highlights that bimolecular activation and unimolecular reactions yield insights into kinetics, demonstrated by experiments such as \(N_2O_5\) decomposition.

If we were to double the concentration of both the haloalkane and the nucleophile, we can see that the rate of the reaction would proceed four times as fast as the initial rate.
