olution is formed when the solute uniformly disperses oughout (or dissolves in) the solvent. The process can be scribed though three steps: 1. separation of solvent-solvent particles, 2. breaking of solute-solute particles, and 3. formation of solute-solvent interactions. e overall energy change for the solution process, AHsin, is sum of the enthalpies of the three steps. Whether AHal is dothermic or exothermic depends on the relative magnitudes of ₁. AH₂, and AH3, where the subscript indicates the step in process corresponding to the enthalpy value. A hypothetical solution forms between a solid and a liquid. The values of the thermodynamic quantities involved in the process are shown in the following table. solute Action Enthalpy separation 17.5 kJ/mol 21.8 kJ/mol separation of solvent formation of solute-solvent interactions -90.7 kJ/mol solute Calculate the enthalpy of solution in kilojoules per mole of solute.

Ethanol has a Kb of 1.22 oC/m and usually boils at 78.4 oC. This means that the boiling point elevation for ethanol is give by the equation: BPE = 1.22 MT where MT is the total number of moles of solute particles per liter of solution How many moles of an nonionizing solute would need to be added to 47.32 mL of ethanol in order to raise the boiling point to 87.1 oC.
