Unformatted text preview: sure from 1 atm to 10 atm. Plot the amount of CO present at equilibrium as a function of pressure. 1687 Estimate the enthalpy of reaction hR for the combustion process of hydrogen at 2400 K, using (a) enthalpy data and (b) KP data.
Answers: (a) 252,377 kJ/kmol, (b) 252,047 kJ/kmol 1688 Reconsider Prob. 1687. Using EES (or other) software, investigate the effect of temperature on the enthalpy of reaction using both methods by varying the temperature from 2000 to 3000 K. 1689 Using the enthalpy of reaction hR data and the KP value at 2800 K, estimate the KP value of the dissociation process O2 2O at 3000 K. 1690 Show that when the three phases of a pure substance are in equilibrium, the specific Gibbs function of each phase is the same. 1691 Show that when the two phases of a two-component system are in equilibrium, the specific Gibbs function of each phase of each component is the same. 1692 A constant-volume tank initially contains 1 kmol of carbon monoxide CO and 3 kmol of oxygen O2 (no nitrogen) at 25C and 2 atm. Now the mixture is ignited and the CO burns completely to carbon dioxide CO2. If the final temperature in the tank is 500 K,...
