A fuel is burned with air as shown below. Calculate the unknown values of the product gas (in mol) for 100% conversion of the fuel, and if the theoretical air is supplied to the furnace. C4H10+13/2O2-->4CO2+5H2O 100mol C4H10 mixed with nair (broken up into 0.21 O2 and 0.79 N2) How many moles of CO2, H20,C4H10,O2 and N2 are there? Solution 1 mol of C4H10 gives 13/2 mol O2, 4CO2 and 5H2O on complete (theoretical) combustion. 100 mol of C4H10 will need 650 mol of O2 for complete combustion and will give: .
