Arich methane (ch4)-air mixture at 298 k and 1 atm enters an adiabatic, constant pressure combustor. measurements indicate that the mole fraction of co and co2 leaving the combustor are equal. determine the equivalence ratio of the reactant mixture and the adiabatic flame temperature assuming that co2, co, h2o, h2, and n2 are the only species in the product pool assume the combustor exit stream is in an equilibrium state. (hint, terate with the online calculator. guess a value for , for example 2, see if co and co2 have the same mole fraction in results, if not, guess another value until co and co2 have the same mole fraction. since it is rich, dmust be greater than 1). show the final solution of and the guessing process. print out the final solution from the calculator when the makes co and co2 have the same mole fraction mole fractions of co and co2 are considered the same as long as the difference between them is less than 0.2 x 10-2
