(PO2, CO2, C4) a) Despite the main reaction in the partial oxidation of propylene (C3H6) to give acrylic acid (C3H4O2), there are two other competing reactions as shown below. These reactions are exothermic. C3H6 + +0C,HO+HO 5 CHOCHO + CO+HO CH+03HO+3CO The feeds consist of 8 mol% of propylene and 92 mol% of oxygen. i) With the appropriate drawing of the process flow diagram, determine the number of process variables values to be specified in order to calculate for the unknown values. (4 marks) ii) Additional information given is that the fractional conversion of propylene is 0.9 and fractional yield of acrylic acid is 0.40. The selectivity of acrylic acid (C3H4O2) to acetic acid production (C2H4O2) is 10. Based on this new information, calculate the molar composition of the reactor output stream. (16 marks)
