Drill equilibrium, acid–base and organic reasoning with answers marked for the working and terminology HSC Chemistry expects.
Using Le Châtelier’s principle, explain the effect of increasing pressure on the equilibrium N₂(g) + 3H₂(g) ⇌ 2NH₃(g).
Increasing pressure shifts the equilibrium toward the side with fewer gas moles. The right side has 2 moles versus 4 on the left, so the system favours the forward reaction, increasing the yield of NH₃.
Full marks — you stated the principle, compared mole counts, and identified the direction and effect on yield. To extend, you could note this changes yield, not the rate or the value of K.
