kinetics of crystalisation

    Cards (5)

    • Gibbs free energy

      Determines spontaneity of reactions in closed systems (no transfer of mass)
    • Gibbs free energy conditions
      • ΔG = 0 (equilibrium)
      • ΔG > 0 (spontaneous in the opposite direction)
      • ΔG < 0 (proceed spontaneously)
    • Gibbs free energy
      • It is affected by the particle's surface (positive) and internal (negative) energies
    • Effect of Temperature
      1. T_m = equilibrium solidification temperature
      2. H_f = latent heat of fusion
    • Heterogenous Nucleation
      1. Ɣ_SL = solid-liquid
      2. Ɣ_SI = solid surface
      3. Ɣ_IL = liquid surface
