WebH 2 O ( l) → H 2 O ( s) is thermodynamically favored at -10 °C. H 2 O ( s) → H 2 O ( l) is non-thermodynamically favored at -10 °C. A non-thermodynamically favored process is considered a process that needs assistance from outside the system. These reactions can be forced to proceed if we apply an external source of energy to it.
