Question:

A rigid insulated tank is divided into two compartments by a membrane. One compartment contains 0.3 kmol of CO2 at 25oC and 100 kPa, and the other compartment contains 4 kmol of H2 gas at 40oC and 300 kPa. The membrane is then punctured and the two gases are allowed to mix. Determine
(a) The mixture temperature
(b) The mixture pressure after equilibrium has been reached.
