The instantaneous rate refers to the rate of a reaction at a specific moment, or instant, during the reaction. It represents how quickly reactants are being consumed or products are being formed at that particular time.
The overall speed at which reactants are consumed and products are formed throughout the entire course of a reaction.
Average Rate: The average speed at which reactants are consumed or products are formed over a specific period of time during the reaction.
An equation that relates the rate of a chemical reaction to the concentrations of its reactants.
