A mixture of propane gas C3H8 and air burns at a constant pressure of 2 bars, reaching equilibrium at a temperature of 2800°K. The quantity of air in the reactants is 20% greater than stoichiometric. If the products of combustion contain only C02, CO, 02 , H20, H2 and N2, show that the degree of dissociation of C02 is approximately 0.32 and calculate the percentage by volume of H2 in the products.
When partial pressures are expressed in bars, the equilibrium constants are given by
