Gibbs energy
In lecture, professor Lavelle plugged in 0 for G in the equation deltaG=deltaH - TdeltaS to figure out at what temperature is G negative. Why does this work?

Re: Gibbs energy
He used 0 for Gibbs Free energy to find the critical point at which the liquid and gas phase both exist. At this temperature deltaG is zero so, a temperature higher than the critical temp found will be spontaneous because deltaG is negative. A temperature lower will mean a positive deltaG so the reverse reaction is favored.
