According to the second law of thermodynamics, for any spontaneous process,
[itex] \Delta S_{uni}> 0 [/itex] .
And for any reversible process,
[itex] \Delta S_{uni}= 0 [/itex] .
This means that no process can be reversible and spontaneous at the same time.
However, what I don't understand is the connection to [itex]\Delta G [/itex]. Suppose I know that [itex] \Delta S_{uni}> 0 [/itex], i.e. the process is spontaneous. Can I use this equation to prove that for the system in question, [itex]\Delta G < 0[/itex]. ? Using only the definition of the terms and knowing that the process is spontaneous?
Thanks!
