Kc = [C]^c[D]^d / ([A]^a[B]^b) for aA + bB ⇌ cC + dD
What each symbol means
| Symbol | What it stands for |
|---|---|
| K_c | Equilibrium constant in concentration terms (units depend on stoichiometry) |
| [X] | Equilibrium molar concentration of species X (mol L⁻¹) |
| a,b,c,d | Stoichiometric coefficients in the balanced equation |
When to use this
Homogeneous equilibrium at constant T. Pure solids and pure liquids omitted from Kc expression. Aqueous solutes as [ ].
