Partial pressure when calculating K

If we want to use partial pressure to calculate equilibrium constant, shell we need to use PV=NRT this equation in order to change partial pressure to the concentration( N/V)?

If you want to calculate Kc, yes.

Alternatively, if the entire equation has only gases, you can just leave them all as pressures and get Kp instead.

You only need to change gases to concentration from partial pressure if an aqueous solution is present in the equation meaning it is not homogenous.

When do you use partial pressure versus concentration when finding equilibrium?
