Answer : Option (B) Pure gas and aqueous solutions.Explanation : The substances that appear in the equilibrium constant expressions are pure gases and aqueous solutions, because, unlike gases and substances in solution, liquids and solids is noted that, in essence, a constant concentration. That is because liquids and solids are virtually incompressible in nature. As the molecules in liquids and solids are placed very close to each other, with very little space to get squeezed and be close to each other. So, as a result, it requires an enormous pressure to perform even a small change in the volume of matter. In most cases, the changes in the volume of a solid or liquid substance, it is ignored.
