The T Δ S 0 term has been estimated for various types of van der Waals molecules and its importance for the stability predictions has been demonstrated. With hydrogen‐bonded complexes the absolute values of Δ H 0 and T Δ S 0 are comparable at 289°K. With true van der Waals molecules the T Δ S 0 term even represents a dominant contribution to Δ G 0 .
