b) It is proposed that a tubular reactor is connected downstream the existing CSTR in part a) in order to achieve a final conversion of 80% as arranged in the figure below, what would be the volume of each reactor if the intermediate conversion is 40%? CAR = 0.005 mol/dm3 Do = 1000 dm3/s X, = 0.4 X2 = 0.8 V , V V
