(F/A) (F/A) stoich 1.0 and an unknow 2. [50 points] A mixture with an equivalence ratio = number of moles of methane (CH4) - and an unknown number of moles of air (0 + 3.76 N) at an initial pressure of 1 atm and initial fuel and air temperatures of 298 K results in one mole of products at 1600 K and with mole fractions of: carbon dioxide (Xco=0.0934) carbon monoxide (Xco 0.0015) water (XH2O = 0.1890), hydrogen (XH = 0.0007) oxygen (X0 = 0.0009), and nitrogen (XN = 0.7144). 2.1 [15 points] write a chemical equation for the combustion process on the basis of one mole of products and find, with appropriate assumptions, the numerical values of the number of moles and the mole fractions of the individual species CH4, O2, and N2 in the reactants. 2.2 [15 points] rewrite the chemical equation in 2.1 considering only the major product species (2.2.1) write a conservation of energy equation for the combustion process, stating additional appropriate assumptions and (2.2.2) find the heat transfer in kj kmol Products' 2.3 [20 points] now reconsider the chemical equation in 2.1 again (2.3.1) find out if the reactions: CO = CO + (O), HO = H + (0), and CO2 + H2 = CO + H2O are in chemical equilibrium and discuss your confidence or lack thereof in the assessment, and (2.3.2) rewrite a conservation of energy equation for the combustion process in view of the consideration of additional products to find the heat transfer in kJ kmol Products
