6) When irradiated with UV light a molecule of A can be excited into a reactive intermediate state A*. Then A* can either be deactivated to A, or decompose into two molecules of B. All steps are first order. i) Using the steady-state approximation show that the consumption of A is first-order overall and derive an expression for the overall effective rate constant in terms of the rate constants of the individual steps. ii) Under the same approximation, derive an equation for the rate at which B is produced which depends only on the initial concentration of A, the time and the rate constants of the individual steps.
