Part C
A solution is formed when the solute unilormly
disperses throughout (or dissolves in) the solvent
The process can be described though three stops
A hypothetical solution forms between a solid and a liquid The vakues of the thermodynamic
Involved in the process are shown in the following table
1 separation of solvent-solvant
particles,
2. breaking of solute-solute particles
and
3. formation of solute-solvent
interactions
Action
Enthalpy

séparation of solute
separation of solvent
formation of solute-solvent interactions -85.7 kJ/mol solute
The overall energy change for the solution process,
AHa is the sum of the enthalpies of the threoe
stepo. Whether AHs endothermic or
exothermic depends on the relative magnitudes of
AH, AH, and AH, where the subscript
Indicates the step in the process corresponding to
the enthalpy value
