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. Enter your answer numerically in kilojoules per mole of solute. ▸ View Available Hint(s) 197| ΑΣΦ 4 Ċ ? AHsoln= Submit kJ/mol
