Reaction rate refers to the speed at which a chemical reaction occurs. It is typically defined as the change in concentration of a reactant or product per unit of time. This can be expressed in various ways, such as: - **For reactants**: Decrease in concentration = -Δ\[A\]/Δt, where \[A\] is the concentration of the reactant.
