### Equilibrium constant for Gas

When writing the equilibrium constant equation for gases, is it ok to use the [] notation as we do for aqueous solutions or do we have to use P (partial pressure) notation?

I'd say you have to use the partial pressure notation since [] implies the concentration of something; my TA said it's okay to use the [] for Kc but use partial pressure notation for Kp
