pressure

• pressure only applies to gas questions
• What is the template answer for effect on equilibrium when pressure is increased?

  When pressure is increased equilibrium moves to the side with fewer moles of gas to oppose the change. Equilibrium moves to the right/left. Yield of ... increases/decreases.
• What is the template answer for effect on equilibrium when pressure is decreased?

  When pressure is decreased equilibrium moves to the side with more moles of gas to oppose the change. Equilibrium moves to the right/left. Yield of ... increases/decreases.
• What is the template answer for when the number of moles (pressure) is equal?

  When the number of molecules of gas in reactants and products is equal, pressure has no effect on the position of equilibrium. Yield is not changed by changing pressure.
