Find the flame temperature of the products of combustion of hydrogen and oxygen whose composition and average specific heats are given in the table below. The reactants enter the adiabatic combustion chamber at 250 K. In this table, Cpp is the average molar specific heat of the component between 298 K and the flame temperature, Cp is the average molar specific heat of the component between 250 K and 298 K, and h, is the heat of formation at 298 K in kJ/kmol.
