Unformatted text preview: tm until 15 percent of H2 dissociates into monatomic hydrogen (H). Determine the final temperature of the mixture. 1679 A mixture of 1 mol of H2O, 2 mol of O2, and 5 mol of N2 is heated to 2200 K at a pressure of 5 atm. Assuming the equilibrium mixture consists of H2O, O2, N2, and H2, determine the equilibrium composition at this state. Is it realistic to assume that no OH will be present in the equilibrium mixture? 1680 Determine the mole fraction of argon that ionizes according to the reaction Ar Ar e at 10,000 K and 0.35 atm (KP 0.00042 for this reaction). Methane gas (CH4) at 25C is burned with the stoichiometric amount of air at 25C during an adiabatic steady-flow combustion process at 1 atm. Assuming the product gases consist of CO2, H2O, CO, N2, and O2, determine (a) the equilibrium composition of the product gases and (b) the exit temperature. 1682 Reconsider Prob. 1681. Using EES (or other) software, study the effect of excess air on the equilibrium composition and the exit temperatur...
