(40 pts) For two elementary, reversible reactions in series taking place in a batch reactor: !! !"! #$ !# !"# #$ Use a differential equation solver (e.g., MATLAB) to solve the problem and plot the concentrations of the species (i.e., CA, CB, CC) as a function of time (up to 50 hours) for the following 3 cases: (a) " = 0.4 #"; $ = 0.01 #"; #" = #$ = 0 (i.e., the two reactions are irreversible). (b) "
