Kp = (Pc)^c(Pd)^d / ((Pa)^a(Pb)^b) for gas-phase reaction
What each symbol means
| Symbol | What it stands for |
|---|---|
| K_p | Equilibrium constant in pressure terms (units depend on Δn_gas) |
| P_X | Equilibrium partial pressure of gas X (same units throughout, often atm or bar) |
When to use this
Ideal gas mixture at constant T. Only gaseous species appear. Solids/liquids omitted.
