In the figure a container is shown to have a movable (without friction) piston on top. The container and
the piston are all made of perfectly insulating material allowing no heat transfer between outside and
inside the container. The container is divided into two compartments by a rigid partition made of a
thermally conducting material that allows slow transfer of heat. The lower compartment of the container is filled with 2 moles of an ideal monatomic gas at 700 K and the upper compartment is filled with 2 moles of an ideal diatomic gas at 400 K. The heat capacities per mole of an ideal monatomic gas are 
 and those for an ideal diatomic gas are  
Q.
Now consider the partition to be free to move without friction so that the pressure of gases in both
compartments is the same. Then total work done by the gases till the time they achieve equilibrium will be
  • a)
    250 R
  • b)
    200 R
  • c)
    100 R
  • d)
    –100 R
Correct answer is option 'D'. Can you explain this answer?

Heat given by lower compartment = 
Heat obtained by upper compartment = 
By equating (i) and (ii)
5(700 -T) = 7(T - 400)
3000 – 5T = 7T– 2800
6300 = 12 T
T = 525K
Work done by lower gas = nRΔT = – 350 R
Work done by upper gas = nRΔT = +250 R
Net work done - 100 R
