For (), what happens to the equilibrium when the pressure is increased at constant temperature?

Answer and explanation

Correct answer: A. It shifts to the right, towards the side with fewer moles of gas

  1. Step 1: The left side has moles of gas and the right side has . Step 2. Raising the pressure favours the side with fewer gas moles, so the position shifts right. Answer: shifts to the right. Why not the others: The equilibrium constant is unchanged, but the position still shifts; the heat of reaction affects temperature changes, not pressure changes.
