1.	A reactor is supplied with 5 moles each of CH3OH and O2, and the following reactions occur, CH3OH + 1/2O2 -> CH2O + H2O and then CH2O + 1/2O2 -> CO + H2O, the conversion of methanol is 80% in first reaction, and conversion of CH2O is 50% in second reaction. How many moles of CO are produced?(a) 1(b) 2(c) 3(d) 4I got this question in an interview.My question is from Processes Involving Multiple Units topic in section The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering
Answer» Right choice is (B) 2 Explanation: Extent of REACTION E1 = (-0.8)/(-1) = 0.8, E2 = (-0.5)/(-1) = 0.5, => MOLES of CO = (0.85)0.5 = 2.
