Definitions:

Reaction-Energy Diagram

A graphical representation showing the energy of a system as reactants transform into products during a chemical reaction, usually highlighting energy barriers and stable intermediates.

Rate-Limiting

Describes the slowest step in a chemical reaction pathway or process, which determines the overall reaction rate.

Exothermic

A chemical reaction that releases energy by light or heat.

Rate Equation

An expression that describes how the rate of a chemical reaction depends on the concentration of the reactants.
