Question

If when you make a solution, all the solute dissolves and the temperature rises, what does allow you to say about:

Delta G(-, +,0,or cannot determine), Delta H(-, +,0,or cannot determine),Delta S(-, +,0,or cannot determine)

The relative strength of the interactions before mixing and after mixing. The solute-solute and solvent-solvent interactions, the solute-solvent interactions, which interactions are stronger.

If when you make a solution, all the solute dissolves and the temperature fall, what does allow you to say about:

Delta G(-, +,0,or cannot determine), Delta H(-, +,0,or cannot determine),Delta S(-, +,0,or cannot determine)

The relative strength of the interactions before mixing and after mixing. The solute-solute and solvent-solvent interactions, the solute-solvent interactions, which interactions are stronger.

Explanation / Answer

If when you make a solution,

If temperature rises:

DG can't determine because it depeds on given temperature. DH is -ve as heat is evolved out. DS is -ve because interactions are increasing in solution during dissolution process.

As temperature of resulting solution increases, we conclude that solute-solute and solvent-solvent interactions are less comparatively than the solute-solvent interactions.

If temperature fall:

DG can't determine because it depeds on given temperature. DH is +ve as heat is evolved out. DS is +ve because interactions are decreasing in solution during dissolution process.

As temperature of resulting solution decreases, we conclude that solute-solute and solvent-solvent interactions are greaer than the solute-solvent interactions.
