Final answer:
The removal of liquid water from a system at equilibrium will cause a shift. If water is a product, the equilibrium will shift to the right. If it is a reactant, the equilibrium will shift to the left.
Step-by-step explanation:
When a system that has already reached equilibrium is disturbed by removing any liquid water, the system will react to such a change in accordance with Le Chatelier's principle. In general, if a product or reactant is removed from the system, the equilibrium will shift in the direction that tends to replace that substance. Therefore, upon the removal of liquid water, the system will rearrange itself to produce more water if water is a product or use up water if it is a reactant.
If water is a reactant, the removal of water would cause the equilibrium to shift to the left, toward the reactant side. Conversely, if water is a product, the removal of water would shift the equilibrium to the right, favoring the forward reaction where more water is produced. If the water does not participate in the equilibrium (like when it's just a solvent), then removing water might not shift the equilibrium at all.
Unfortunately, without a specific reaction given, we can't determine the exact direction of the shift. However, considering the principles discussed, the most likely answer is either it will shift to the right or to the left depending on whether water is a product or a reactant respectively.
