WebAug 25, 2024 · The equilibrium expression for the synthesis of ammonia. 3H 2(g) + N 2(g) 2NH 3(g) can be expressed as. Kp = P2NH3 PN2P3H2. or. Kc = [NH3]2 [N2][H2]3. so Kp for this process would appear to have units of atm –2, and Kc would be expressed in mol –2 L 2. And yet these quantities are often represented as being dimensionless.
