Pressure and the Position of Equilibrium

Pressure changes only affect reactions involving gases. To predict what happens after a change in pressure, we must look at balanced equations to see how many gas molecules are on each side of the equation.

Illustrative background for Increase pressureIllustrative background for Increase pressure ?? "content

Increase pressure

  • The position of equilibrium will shift to favour the reaction that produces the fewest gas molecules.
Illustrative background for Decrease pressureIllustrative background for Decrease pressure ?? "content

Decrease pressure

  • The position of equilibrium will shift towards the side of the reaction that produces the most gas molecules.
