Reaction rate, the speed at which a chemical reaction proceeds it is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time alternatively, it may be defined in terms of the amounts of the.
