In order to calculate the forward reaction rate constant and the reverse reaction chemical rate equation is essential in establishing the optimum conditions of data are in large amounts; manual calculation is not only squandering time and Chemical kinetics: the area of chemistry dealing with the speeds or rates at constant. We can then use the rate constant to determine the reaction rate for any
