The answer is most likely No, because most solvents are liquid or solid. Liquids and solids are not included in the equilibrium constant expression, because they are essentially incompressible, without varying concentration.

Although solvents can be gaseous, I doubt that No is the wrong answer, because Sometimes and Not Always have the same meaning. We can only select one answer.
