Can someone summarize the piston example that was discussed in lecture?

i dont know if ur talking about this one. but basically it explained that increasing pressure by adding an inert gas does not change which side the reaction shifts to

my impression of the example was that the displacement of the piston (moving out) can be used to calculate the change in energy of the system; if you calculate the work function of the piston movement then the energy would've decreased by an amount equal to the energy lost as work done by the system.

In expansion work, the work done to the surroundings is the energy lost to push against the external pressure. This is one way you can change the energy of the system.
