1648C What is the importance of the van't Hoff equation? 1649C Will a fuel burn more completely at 2000 or 2500 K? 1650 Estimate the enthalpy of reaction hR for the combustion process of carbon monoxide at 2200 K, using (a) enthalpy data and (b) KP data. 1651E Estimate the enthalpy of reaction hR for the combustion process of carbon monoxide at 3960 R, using (a) enthalpy data and (b) KP data. Answers: (a) 119,030
Btu/lbmol, (b) 119,041 Btu/lbmol 1641 A mixture of 2 mol of CO2 and 1 mol of O2 is heated to 3200 K at a pressure of 2 atm. Determine the equilibrium composition of the mixture, assuming that only CO2, CO, O2, and O are present. 1642 Air (21 percent O2, 79 percent N2) is heated to 3000 K at a pressure of 2 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 m...
