A reactor is supplied with 25 moles of C, and it undergoes following reactions C + 0.5O2 -> CO and C + O2 -> CO2, if 13 moles of CO2 was produced and 5 moles of C remains unreacted, what are the number of moles of CO produced?(a) 1(b) 3(c) 5(d) 7This question was addressed to me in unit test.Query is from Processes Involving Multiple Units in section The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering |

Answer» RIGHT choice is (d) 7 For explanation: Extent of second reaction = (13 – 0)/1 = 13, => moles of C reacted in second reaction = 13*1 = 13, => moles of C reacted in first reaction = 25 – 13 – 5 = 7, => extent of first reaction = (0 – 7)/(-1) = 7, => moles of CO produced = 7*1 = 7. |
