1636 Estimate KP for the following equilibrium reaction at 2500 K: CO H2O CO2 H2 At 2000 K it is known that the enthalpy of reaction is 26176 kJ/kmol and KP is 0.2209. Compare your result with the value obtained from the definition of the equilibrium constant. 1637 A constant-volume tank contains a mixture of 1 kmol H2 and 1 kmol O2 at 25C and 1 atm. The contents are ignited. Determine the final temperature and pressure in the tank when the combustion gases are H2O, H2, and O2. 1630 A mixture of 3 mol of N2, 1 mol of O2, and 0.1 mol of Ar is heated to 2400 K at a constant pressure of 10 atm. Assuming the equilibrium mixture consists of N2, O2, Ar, and NO, determine the equilibrium composition.
