partial pressure

Do we treat a change in partial pressure the same way we would a change in molar concentrations?

Hi! Yes you do when dealing with Kp because the value of Kp will not change with pressure changes, but it can be used to calculate partial pressures.

Just like Fiona said, K for gases and aqueous solutions are calculated the same way, just different units are used. Molarity for concentration, and generally bar for partial pressure.
