plz show all work. Thermo departure function problem.

5 = A well-insulated rigid vessel with rigid walls is divided into two compartments of equal volume 0.1m. The partition permits transfer of heat. One side contains 200 moles of a nonideal (diatomic, and in ideal gas state, Cy =R) gas at 300K and the other side contains perfect vacuum. The partition is ruptured and after sufficient time for the system to reach equilibrium, the temperature and pressure are uniform throughout the system. The gas follows a virial (like) equation of state: a RT a P= 2 Where a = 92 x 105 atm cm6/mol?. Solve for the final pressure P and temperature T
