If a solute dissolves in an endothermic process Question 10 options: a) the solute must be a gas. b) the entropy of the solution must be greater than that of its pure components. c) H bonds must exist between solvent and solute. d) the entropy of the solution is immaterial. e) strong ion-dipole forces must exist in the solution.

If a solute dissolves in an endothermic process the entropy of the solution must be greater than that of its pure components.

Explanation:

An endothermic process is defined as the process in which heat is absorbed by the reactant molecules taking part in a chemical reaction.

But in an endothermic process it is not possible to determine the type of bond present in the chemical atoms.

Also, we know that a spontaneous reaction between the solute and solvent leads to dissolution of solute particles. For such type of reactions, .

We know that,

          .......... (1)

For this, heat at constant pressure, (for an endothermic process).

According to equation (1), more is the entropy of solution () more will be the negative value of .

Thus, we can conclude that if a solute dissolves in an endothermic process the entropy of the solution must be greater than that of its pure components.
