Rate Of Reaction
What is Rate Of Reaction?
The rate of a chemical reaction is the change in the concentration of a reactant or product per unit time, typically expressed in units of mol L⁻¹ s⁻¹. It depends on factors such as reactant concentrations, temperature, pressure (for gases), catalysts, and surface area (for heterogeneous reactions). The relationship between rate and concentration is expressed in the rate law: rate = k[A]ᵐ[B]ⁿ, where k is the rate constant and m, n are the reaction orders.
