How do you write equilibrium expressions

WebUsing the partial pressures of the gases, we can write the equilibrium expression, denoted as K p because it is the result of pressures, and calculate for the system. For example: 2 NH 3 (g) ⇌ N 2 (g) + 3 H 2 (g) K p = Heterogeneous Equilibria. A heterogeneous equilibrium is a system in which the reactants and products are found in … WebWriting equilibrium expressions Kc and Kp when molar concentrations are known and Kp when partial pressures are known. If in a heterogeneous equilibrium if at least one of the reactants or products is a gas we can write a Kp expression. For homogeneous equilibrium gases we may write a Kp expression.
