I dont understand why if you increase the pressure on a system of gasses, the reaction does move towards the end that has a lesser number of gas mols. It seems that it would make more sense for a higher pressure to change the K value so that the gasses take up "less space"
I believe this has to do with the PV=nRT equation. If you increase the Pressure, you are decreasing the Volume, and since volume and number of moles are proportional to each other (V=n/M) then the concentration will increase, thus causing the reaction to go in the other direction.
