- van deer waals equation of real gas state: P=VnbnRTa(V2n2) - Critical temperature: Tc=27bR8a 1. (2 pts) Ideal gases are occupied in compartment A and compartment B in the condition below (left). Two compartments are separated by a movable adiabatic wall, which does not flow heat and molecules. When the stopper is released, the wall moves to the middle of entire compartment as shown below. What is a final pressure of compartment A and compartment B, respectively, after reaching mechanical equilibrium? Note that molecules cannot pass through the wall. If necessary, use R=8.314JK1mol1.
