Calculate Equilibrium Constant (Kp)
About Kp
Kp is the equilibrium constant expressed in terms of partial pressures for gas-phase reactions.
From Kc:
Kp = Kc × (RT)^(Δn)
From Gibbs Free Energy:
Kp = e^(-ΔG°/(RT))
From Partial Pressures:
Kp = (P_C^c × P_D^d) / (P_A^a × P_B^b)
Where Δn is the change in moles of gas (products - reactants), R is the gas constant, and T is temperature in Kelvin.
