A reaction network is given below, assuming each reaction to follow unimolecular kinetics. Plot the normalized concentrations (e.g. C/CAO). kl k3 k4 k5 k = 0.0133; k2 = 0.0108; k3 = 0.0024 k4=0.0024; ks = 0.008 All k values are specified in min- Derive analytical expressions for the concentration of species A, B, C, and D. To get a time dependent plot at the end you may assume that no B, C or D is present initially.
