100 moles of C4H10 undergoes complete combustion in excess air. First, show the degree of freedom analysis for this process. Then calculate the composition (mole fractions) of the stack gas on a wet basis for the following three cases: (1) theoretical air supplied and 100% conversion of C4H10; (2) 20% excess air and 100% conversion. The energy released in the combustion of C4H10 is 49.2 kJ/g. You require 1000 kJ of heat energy to run a boiler. How much CO2 (in g) will you create by combustion of the required C4H10.
