Consider the Air-Fuel Mixture introduced in an Internal Combustion Engine at 298 K, which is heated to 350 K before Combustion. The Mixture is Ignited, and the Combustion products are formed with the Maximum temperature of the Products being 2000 K. Assume that proper combustion took place and all the Reactants are combusted, with no Sub-Products formed. Consider the following for N2 in the Combusted Product, which is left unreacted. (Assume the Process happened at Constant Pressure)
