2. The reaction is given below at constant temperature in a continuous

2. The reaction is given below at constant temperature in a continuous stirred tank reactor: k A+B+C+D -1A = (6h-)CA [kmol/mh] The concentrations of A and B in the feed are 0.5 and 1 kmol/m, respectively. The molar feed flowrate of A is 100 kmol/h. The costs of reactant A and B are specified as 1 and 1.5 TL/kmol. Cost of reactor including installation, auxiliary equipment, instrumentation, etc. is 1 TL/mh. The selling prices of main product C and side product D are 0.4 and 0.25 TL/kmol, respectively. a. Find the optimum reactor size and conversion for maximum annual profit. b. Find the production rate and unit cost of main product C for these conditions.
