Gaseous Equilibria

• This section covers how we manage gases in calculating the equilibrium constant and how an equilibrium yield is affected by the partial pressures of reactants and products
• Many industrial process involve reactions between gases so this application has important consequences for controlling reaction conditions
• In the generic example above, if all the substances are gases, we can show the equation with that state symbol

aA (g) + bB (g) ? cC (g) + dD (g)

• We can write a different equilibrium expression in terms of the?partial pressure?of the gases
• This equilibrium constant is called?Kp?and is defined as follows

Equilibrium expression linking the partial pressures of reactants and products at equilibrium

• Solids?and?liquids?are ignored in?Kp?equilibrium expressions
• The?Kp?of a reaction is constant and only changes if the?temperature?of the reaction changes
