Chapter 12, Problem 14RQ

Interpretation Introduction

Interpretation:

The reason for the positive value of $\Delta H_{\text{soln}}$ in the formation of an ethanol-hexane solution is to be explained.

Concept Information:

Intermolecular forces of attraction are the forces between the solute and the solvent that binds them together. For example, van der Waals forces, hydrogen bonding, and London forces.

The enthalpy of a solution ($\Delta H_{\text{soln}}$) is defined as the enthalpy change, in which there is an endothermic change in the solute as well as in the solvent with the formation of new bonds that form a new compound in the solution with an exothermic reaction and the release of heat.
