Question

No water molecules are moving across the barrier between the two compartments. a.A net movement of water molecules continues to add water to the right-hand compartment. b.None of the answer options is correct. c.A net movement of water molecules begins to add water to the left-hand compartment. d.Water molecules move randomly across the barrier with no net addition of water to either side.

Answer 1

Answer:

-Water molecules move randomly across the barrier with no net addition of water to either side.

Explanation:

Which of the following best describes conditions at equilibrium?

-No water molecules are moving across the barrier between the two compartments.

-A net movement of water molecules continues to add water to the right-hand compartment.

-A net movement of water molecules begins to add water to the left-hand compartment.

-Water molecules move randomly across the barrier with no net addition of water to either side.

-None of these choices accurately describe conditions at equilibrium.

An equilibrium can be described as condition in which there is no net movement of substances across two sides. For example, if A and B are in equilibrium for a particular molecule, the rate of movement of the molecule from A to B is the same as the rate of movement of the molecule from B to A.

Hence, the option that best described conditions at equilibrium is the one in which water molecules move randomly across the barrier with no net addition of water to either side.
