Question:

A stoichiometric mixture of carbon monoxide and air reacts in a combustion chamber, forms exhaust products at \(3000 \mathrm{~K}\) and 1 bar. If the products are in chemical equilibrium, but no reactions occur between the nitrogen and the oxygen, show that the molar fraction of carbon monoxide is approximately 0.169 . The products of combustion now enter a heat exchanger where the temperature is reduced to \(1000 \mathrm{~K}\). Calculate the heat transfer from the products per amount of substance of \(\mathrm{CO}_{2}\) in the gases leaving the heat exchanger if dissociation can be neglected at the lower temperature.

\(\left[-399.3 \mathrm{MJ} / \mathrm{kmol} \mathrm{CO}_{2}\right.\) ]
