Equilibrium Constant

Postby Alma Cruz 1A » Wed Jul 19, 2017 5:49 pm

I was reading over the course reader and was wondering if there is a difference between K_c=[C]^c[D]^d/[A]^a[B]^b and K_p=[Products]/[Reactants] ?

Thank you in advance.

There is no significant difference between Kc and Kp since both of them are used to describe equilibrium constant. The only difference is that when talking about reactions in gas phases, concentration should be replaced by partial pressure.

Could you please explain more when to use Kc or Kp. Because don't all reactions when finding either K occur in gas phases?
