partial pressure v concentration

Postby Karina Koo 2H » Wed Jan 16, 2019 5:40 pm

If we have a reaction that includes both gas and aqueous states, do we use partial pressure or concentration?

You can always use either but make sure you use Kp for partial pressure and Kc for concentration.

I believe partial pressure can only be used for homogeneous gaseous reactions. Using Kp and Kc also depends of what information you've been given, like whether or not the problem lists things in M or atm.

Is it ok to just write K or do we have to specify which K we are using?

My TA mentioned that we can just write K, unless stated specifically to use partial pressure or concentration. But, I would just write Kp or Kc just to make sure!
