concentration vs partial pressure

Postby alanaarchbold » Sun Jan 13, 2019 3:33 pm

Would it be wrong if on a test we used concentration in the K equation if the reaction refers to gases? Or would we have to use partial pressure? (and vice versa for aqueous)

Hello,
I believe in the last lecture Professor Lavelle said we can give an answer in partial pressure or concentration if the question does not specify, but if the question wants the Kc we need to give it in concentration, but we can use partial pressure to find the concentration with P=(conc) RT. Hope this helped!

You are able to use concentration when you are referring to gases as well.
