Use the heat of vaporization ( H= 30.91) and the entropy of vaporization [S = 93.2] to calculate the boiling point  of liquid bromine.

The enthalpy change for the reaction of 60 mL of ethylene with 60 mL of  hydrogen gas (H2) at 1.5  pressure is  (Change) H= -0.37 .

I can't seem to figure out these problems

First problem:

?G = ?H - T?S

At the boiling point, there is an equilibrium between liquid and gas phase:

0 = 30,910 - T (93.2)

T = 332 K
