Assuming K

Let's say there's a question that asks you if a chemical reaction is at equilibrium, and it gives you a reaction and K-value but doesn't specify if the K is Kc or Kp. Then, it gives you the partial pressure concentrations of the reactants and products. Is it safe to assume then, that the K-value given is a partial pressure constant? Or should we assume that it's a concentration in mol/L, and should therefore convert that number?

If they do not specify I think it is safe to say that it would be Kp (partial pressure). From my understanding the partial pressure K is actually the more "traditional" K value that then has to be converted to Molar concentration.

Doesn't K value (by itself) normally imply that you should concentrations thought?
