The vapor pressure of HN3 is 58 Torr at -22.75 C and 512 Torr at 25C. Find the standard enthalpy of vaporization, standard entropy of vaporization, the standard free energy of vaporization.

I know how to find the first two, but for some reason I can't find the third one...Is the equation for it lnP=-G/(RT). If so, what unit is P in and which P should I use and is R 8.3145 and what temperature do I use?
