Relation Kp and Kc (Kp = Kc (RT)^Δn)
jee-mainjee-advancedneet-ug
Kp = Kc (RT)^Δn
What each symbol means
| Symbol | What it stands for |
|---|---|
| R | Gas constant matching pressure units (e.g. 0.0821 L·atm·mol⁻¹·K⁻¹) |
| T | Absolute temperature (K) |
| Δn | Moles of gaseous products − moles of gaseous reactants (from balanced equation) |
When to use this
Ideal gases; Kc uses mol L⁻¹ and Kp uses atm if R = 0.0821. Δn counts only gases.
