Ethane is burned with 50% excess air. The percentage conversion of the ethane is 90%; of the ethane burned, 25% reacts to form CO, and the balance reacts to form CO2. Calculate the molar composition of the stack gas. n(mol C,H,) ng(mol O,) ny(mol N2) 100 mol C,H 50% excess air no(mol) 0.21 mol O/mol 0.79 mol N/mol n,(mol CO) ng(mol CO,) no(mol H,O) C,H, +0, 2C0, + 3H,0 C,H +0, - 2CO + 3H,0
