An equimolar mixture of liquid n-hexane and n-heptane is at 80 C. a. Using the Gibbs Phase rule, show that the pressure of this fluid is unknown (i.e. one degree of freedom remains). (3 points) b. Suppose the pressure of the liquid is increased and the mixture behaves as an ideal solution.. At which pressure will the first bubble of vapor form and what is the composition of the vapor phase?
