Question

Consider the following simple reaction mechanism where both reactions follow first-order kinetics and R is the desired product: 𝐴 1 -> 𝑅 2 -> 𝑆 For this reaction mechanism, the time at which the desired product R reaches its maximum (tmax), and the value of the maximum achievable concentration of desirable product R (CR,max) are given by: tmax = ln(k1 k2 ⁄ ) (k1− k2) ⁄ CR,max = CA0[k1 k2 ⁄ ]k2 (k2−k1) ⁄ A laboratorial test carried out with an initial concentration of reactant A of 1150 mol m-3 , resulted in values of tmax and CR,max of 6.6 min and 957.82 mol m-3 , respectively. Based on this information, calculate the value of the rate constant k2 in hr-1 . Hint: the solution to this question requires the algebraic manipulation of the equations provided.
