Part C A solution is formed when the solute uniformly disperses throughout (or dissolves in) the solvent. The process can be described though three steps: 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. 1. separation of solvent-solvent particles, 2. breaking of solute-solute particles, and Action Enthalpy separation of solute 18.5 kJ/mol 3. formation of solute-solvent interactions. separation of solvent 19.8 kJ/mol formation of solute-solvent interactions -84.7 kJ/mol solute The overall energy change for the solution process, AHsoln , is the sum of the enthalpies of the three steps. Whether AHsoln is endothermic or exothermic depends on the relative magnitudes of AH1, AH2, and AH3, where the subscript indicates the step in the process corresponding to the enthalpy value.
