Volume/Pressure Stress via Q vs. K

The idea
Compressing a gas equilibrium raises every concentration, changing Q unless gas moles are equal on both sides, so it shifts toward the side with fewer moles.
In practice
Compressing N2 + 3 H2 ⇌ 2 NH3 shifts the mixture toward NH3, the side with fewer gas moles.
Where people slip
Equal gas moles on both sides means no shift from a volume change, since Q never moves.
