The following liquid-phase process takes place in a PFR: \mathrm{A} \stackrel{1}{\longrightarrow} 2 \mathrm{~B} \stackrel{2}{\longrightarrow} 3 / 2 \mathrm{C} \text {. } The first reaction is simple, but the second one is 0th order (not second!), i.e. r2 = k2. a) Analyse the evolution of the mixture along the length of the reactor. b) If B is the desired product, what space-time of the reactor will optimize the yield (this is also the induction time)? What is the maximum conversion? What is the overall selectivity of B with respect to C at the optimal space time? c) Plot the concentration profiles until the point where [B] = 0.Parameters: k₁= 1.1 min¹; k2 = 0.2 M-min'; [A]o = 0.4 M.
