Solve the below problem:
Q: A rigid container initially contains 2 kmol of carbon monoxide and 2 kmol of oxygen at 25?C, 100 kPa. The content is then heated to 3000 K at which point an equilibrium mixture of CO2, CO, and O2 exists. Disregard other possible species and determine the final pressure, the equilibrium composition and the heat transfer for the process.
