Consider a system of two continuous stirred tank reactors in series (Figure PI, 6), where the following enciothermic reaction takes place: A+catalystB (a) Identify the control objectives for the operation of the two CSTR. (b) Classify the variables of the system into inputs and outputs and subsequentiy elassify the inputs into disturbances and manipulated variables rand the outputs into measured and unmeasured outputs. Is this a SISO Or a MIMO system? (c) Develop a feedback control configuration that satisfies your objectives using a composition analyzer at the exit stream of the second CSTR. (d) Develop an inferential control configuration that uses temperatures and flow rates only, assuming that a composition analyzer is not available. (e) Develop a feedforward control configuration that can also use composition analyzers if they are needed. (f) In your opinion, which system is easier to control, the two-csTR system shown in Figure PI.6 or an equivalent one-CsTR system that achieves the same conversion? Explain qualitatively why
