What happens to the concentration of
SO2(g) when the total pressure on the equilibrium reaction
2 SO2(g) + O2(g) <---> 2 SO3(g) is increased (by compression)?
I thought it remained the same but that was incorrect.

Remember what I told you in the last response. Le Chatelier's Principle--with gases-- the system shifts to the side with the fewer moles of gas. There are three moles on the left and 2 on the right. Goes to the right.
but what happens to the concentration of SO2? does it decrease?
It decreases, yes. The amount of moles is the same as the concentration of the compound. It shifts to the right and causing all molecules to shift; therefore it decreases.
