The change in the Gibbs free energy for dissolving solute in a saturated solution is a. positive. b. negative. c. zero. d. positive at low temperatures and negative at high temperatures.

Respuesta :

Answer:

Negative

Explanation:

For a solution to form, the change in Gibbs free energy must be negative for dissolving. When a solute dissolves in a saturated solution, ΔH(enthalpy change) is negative and ΔS(entropy change) is positive, giving rise to a large negative ΔG(change in gibbs free energy) and a very high solubility.

Answer:

Positive

Explanation:

The solution is supersaturated. This means that no more solute can be dissolved. If the substance does not dissolve then the process is not spontaneous. If the process is not spontaneous then Delta G is positive
