Pressure

• N2 (g) + 3H2 (g) ->2NH3

  4 moles ----- 2 moles

  If pressure is increased the equilibrium will move to the right to lower the pressure
• 2A (g) + B (g) <=> X (g) + Y (g)

  If pressure is increased, which side does the equilibrium move to?

  Right
• 2X(g) <=> 2A(g) + B(g)

  If pressure is increased, which side does the equilibrium move to?

  left
• B(g) <=> X(g) +Y(g) + Z(g)

  If pressure is increased, which side does the equilibrium move to?

  left
