For the equilibrium N₂(g) + 3H₂(g) ⇌ 2NH₃(g), increasing the pressure at constant temperature will

Answer and explanation

Correct answer: A. shift the equilibrium to the right

  1. Step 1: By Le Chatelier's principle, higher pressure favours the side with fewer gas moles (2 versus 4).
Answer
shift the equilibrium to the right.
Why not the others: shift the equilibrium to the left: the left side has more gas molecules, which pressure disfavours. have no effect on the position of the equilibrium: the number of gas moles differs on each side, so pressure matters. change the value of the equilibrium constant: Kc changes only with temperature.
