How to Calculate the Equilibrium Constant | Both Kc and Kp

Equilibrium Partial Pressures and Kp

Besides being described via equilibrium concentrations, equilibria involving gases can also be described in terms of Equilibrium Partial Pressures, (instead of concentrations).

WHY ?

Because we can manipulate the Ideal Gas Law…

 Concentration, C, is moles / L , right?

 And so is “n / V” in the Ideal Gas Law (moles / L).
