Submitted : Spring 2011 This project calculated the adiabatic flame temperature of a combustion reaction of pure methane and oxygen, assuming that all of the heat liberated by the combustion reaction goes into heating the resulting mixture. Mole fractions of methane to oxygen were computed from 0.05 to 0.95, in increments of 0.05, and then an integral was computed was computed with respect to T using the moles of product produced or leftover moles of reactants from the starting mole fraction times the specific heat of each respective gas from 25 to T_{A}. This is then set equal to the heat produced by the reaction and solved to equal zero. The quadratic formula is then used to solve for T_{A}. Based on the values of T_{A} obtained for each mole fraction from 0.05 and 0.95, the highest adiabatic flame temperature evaluated occurs at a mole fraction of 0.35.
