O The initial rate is the same for the same reaction at the same temperature even at varying initial concentrations. O Rate constant is the same for the same reaction mechanism at the same temperature.
Why is the initial rate more experimentally useful than the average rate?
O Average rates change depending on the nature of the reactants and products.
O The initial rate of the reaction is the fastest rate and most easily observed.
O Instantaneous and average rates are more difficult to obtain experimentally.
O There are far fewer external factors that could affect the initial rate than the average rate.
