According to the 2nd law of thermodynamics, a spontaneous process will occur (or rather: is very likely to occur) if [tex] \Delta S > 0[/tex].(adsbygoogle = window.adsbygoogle || []).push({});

A chemical process occurs if [tex] \Delta G < 0[/tex], where [tex] G = H - TS[/tex].

Example:

H = -100 kJ

T = 1 K

S = -10 kJ/K

so [tex] \Delta G = - 190 kJ[/tex]. In this example, [tex] \Delta G < 0[/tex] but [tex] \Delta S < 0[/tex].

Doesn't this contradict the 2nd law?
