Please please help 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)

Apeak with a retention time of 407 s has a width at half-height (w1/2) of 7.6 s. a neighboring peak is eluted 17 s later with a w1/2 of 9.4 s. a compound that is known not to be retained was eluted in 2.5 s. the peaks are not baseline resolved. how many theoretical plates would be needed to achieve a resolution of 1.5?
