Qin AIR O2, N2, O, NO 3000 K 1652 Using the enthalpy of reaction hR data and the KP value at 2400 K, estimate the KP value of the combustion process H 2 1 O2 H 2O at 2600 K. Answer: 104.1 2 1653 Estimate the enthalpy of reaction hR for the dissociation process CO2 CO 1 O2 at 2200 K, using 2 (a) enthalpy data and (b) KP data. 1654 Estimate the enthalpy of reaction hR for the dissociation process O2 2O at 3100 K, using (a) enthalpy data and (b) KP data. Answers: (a) 513,614 kJ/kmol, (b) 512,808 kJ/kmol 1655 Estimate the enthalpy of reaction for the equilibrium 2O2 CO2 2H2O at 2500 K, using reaction CH4 (a) enthalpy data and (b) KP data. Reaction chamber FIGURE P1642 Air (21 percent O2, 79 percent N2) is heated to 5400 R at a pressure of 1 atm. Determine the equilibrium composition, assuming that only O2, N2, O, and NO are present. Is it realistic to assume that no N will be present in the final equilibrium mixture? 1644E Reconsider Prob. 1643E. Use EES (or other) software to obtain the equilibrium solution. Compare your solution technique with that used in Prob. 1643E. 1643E Phase Equilibrium...
