Concentration vs. Partial Pressure

Postby Leonardo Le Merle 1D » Tue Jan 21, 2020 3:31 pm

When calculating K, should we always express it for gases in terms of partial pressure? Or should we try to convert to concentration (n/V) for them as well?

I think it depends on the values the problem gives you and on the context of the problem – if the problem gives you atm, for instance, then you would most likely find the equilibrium constant in terms of partial pressure, unless it explicitly states for you to convert it to Kc.
