Determine the heat added or liberated per 100 mole of gas mixture.

1. A gas mixture, of composition: 12.8 mol% CO(g), 3.7 mol% CO2(g), 5.4 mol% O2(g), and 78.1 mol% N2(g), is passed through a bed of incandescent (assume pure carbon) coke to produce a gas consisting only of CO and N2. The two reactions that occur, both go to completion, are: CO2(g) + C(s) 2CO(g) 2C(s) + O2(g) 2CO(g) The gas mixture enters and leaves the coke bed at 875C. Determine the heat added or liberated per 100 mole of gas mixture. Hint: Carbon (C) is a reactant and it is totally consumed.
