Kc and Kp

Postby Andrea_Torres » Sun Jan 12, 2020 4:47 pm

What is the difference between using Kc and Kp?

I believe Kc deals with Equilibrium Constant concentrations while Kp deals with Equilibrium Constant partial pressures

Kc also uses brackets whereas Kp uses parentheses

Kc is used for aqueous solutions and Kp is for gases.

Kc is the equilibrium constant in concentrations and Kp is the equilibrium constant for gases which is in partial pressure.

When solving for Kp do we have to represent the products and reactants as partial pressures?

Both are equilibrium ocnstants, but Kc is calculated from concentrations, and Kp is calculated from partial pressures.

Kc is solved using concentration while Kp is solved using partial pressures.

Kc is often the equilibrium constant found in concentrations while Kp deals with the partial pressures.
