Question

12 g of C(s), solid graphite, and partial pressure O₂(g) - 100 bar are held in a thermally insulated, 1.0 L rigid container at 298K. Combustion of the graphite is initiated, and the combustion proceeds until all the graphite is consumed, CO₂(g) is the only combustion product. Determine the final temperature of the O2/CO2 mixture, you may assume enthalpy of combustion is independent of pressure, heat capacity is entirely that of the contents of container (container does not contribute to it), that any relevant heat capacities are independent of temperature and pressure, all gases are ideal.

Answer 1

I hope you can understand the solution.

Thank you!!!
