Problem 2 (40 points): Determine the adiabatic flame temperature and equilibrium composition for constant-pressure combustion of n-heptane/air mixture at 298K and equivalence ratios =0.7, and 1.4. (i) For =0.7, assume the product species as CO2,H2O,N2, and O2. (ii) For =1.4, consider the product species as CO2,H2O,N2,CO, and H2, and use the watergas shift equilibrium reaction (see Turns book)
