A 1 0 % rich mixture of Heptane ( C 7 H 1 6 ) and air is initially at a pressure of 1 bar

A 10% rich mixture of Heptane (C7H16) and air is initially at a pressure of 1 bar and
temperature of 100C, and is polytropically compressed through a volumetric ratio of 6 to
It is ignited and adiabatic combustion proceeds at constant volume. The maximum
temperature reached is 2627C and at this temperature the equilibrium constants are
pH2OPCOPCO2PH2=6.72
PCO2PO2PCO2p0=0.054
p0=1 bar is a reference pressure for the equilibrium constants. if the constituents of the
gas are CO2,CO,H2O,H2,O2 and N2 :
(a) Calcuate the reaction equation without dissociation
(b) Calculate the equilibrium product composition.
(c) Verify that approximately 30.2% of the carbon has burned incompletely.
Notes:
the number of moles is not conserved in this reaction!
You may use any method to solve the (nonlinear) equations you derive.
