Answer: b. the volume of water vapour increases
Explanation:
when there's an increase in concentration, the equilibrium favours the forward reaction, more product is produced, froward reaction is faster
Answer: A. The greater the pressure, the more of gas that will dissolve.
Explanation: Increasing pressure increases the solubility of gases. It has little effect on the solubility of liquids and solids.
Answer: The magnitude of the equilibrium constant, K, indicates the extent to which a reaction will proceed: If K is a large number, it means that the equilibrium concentration of the products is large. ... If K is a small number, it means that the equilibrium concentration of the reactants is large.

In this problem, the solute is sodium chloride, the salt while the solvent which comprise of a larger mass in the solution is water. When the solvent volume is decreased which is related to its mass, with the solute mass being held constant, then the concentration of salt increases. This is called concentration method.
