The entropy change (ΔS) for this process is positive. When a crystalline solid like NaCl dissolves, the ions move from a highly ordered solid lattice to a more disordered aqueous state, increasing randomness. The free energy change (ΔG) for this process is negative because it is described as a spontaneous process. For any process to be spontaneous at a given temperature and pressure, the change in Gibbs free energy must be less than zero (ΔG < 0).
