The equations of the sublimation and the vaporization curves of a particular material are given by

ln P = 0.04 -6/T (sublimation)

ln P = 0.06 - 4/T (vaporization)

where P is in atmospheres.

a) find the temperature of the triple point.

b) show the specific lateant heats of vaporization and sublimation are 4R and 6R respectively

c) Find the latent heat of fusion.

Can anyone give me somewhere to start on this problem? The problem is in the Thermodynamic Potential chapter, so I am assuming I should use the Helmholtz or the Gibbs function somehow. Any help would be awesome!

Thanks
