Can someone please help me pls no links :( I understand you have to use the equation Delta g= delta h - temperature*delta s The vaporization of bromine requires 31.0 kJ/mol and an increase in disorder (delta S=93.0 J/(mol*K)). At what temperature will this process be spontaneous?
Br2 (l) yields Br2 (g)
