Key Concepts

Reaction Mechanism

A reaction mechanism is a detailed sequence of elementary steps by which a chemical reaction occurs. It explains not only the overall transformation of reactants to products but also the order in which bonds break and form, providing insight into the intermediates and transition states involved in the process.

Elementary Reaction

An elementary reaction is a single-step process where the rate law can be directly written based on the stoichiometry of the reaction, meaning that the reaction order with respect to each reactant corresponds to the number of molecules involved in that step.

Rate-Determining Step

The rate-determining step is the slowest step in a multi-step reaction mechanism. Because it limits the overall rate, the rate law for the entire reaction is typically derived from this step, with the concentrations of the reactants in this slow step directly influencing the overall reaction rate.

Steady State Approximation

The steady state approximation is used when an intermediate in a reaction mechanism is produced and consumed at nearly equal rates. By assuming its concentration remains constant over time, this approximation allows the elimination of the intermediate’s concentration from the rate law, simplifying the analysis.

Pre-equilibrium Approximation

The pre-equilibrium approximation applies when an early step in a reaction mechanism is fast and reversible, establishing an equilibrium before a slower subsequent step. This equilibrium condition permits the use of an equilibrium constant to replace the intermediate concentration in the rate law, linking it to the concentrations of reactants.
