Homework Statement

The equilibrium vapor pressures of liquid gallium areT(K) 1302 1427 1623
p(torr) 0.01 0.1 1.0 a-Calculate the enthalpy, entropy and Gibbs energy changes for the process
b-Calculate the standard enthalpy, entropy, and Gibbs energy changes for the vapozation of liquid gallium at 1427 K. Under standard conditions the pressure of the gallium is 1 bar. Will liquid gallium 1427 K spontaneously form vapor with a pressu of 1 bar?

<br /> Ga(l) \rightarrow Ga(g, 0.1 torr)<br />

at 1427 K.

Heres what I derived so far

<br /> dG=Vdp<br /> dG=\frac{RT}{p}dp<br /> \Delta G=RTln\frac{p_2}{p_1}<br />

I'm not sure how to get p_1 to solve for \Delta G

I have solved this problem. It was quite simple actually.
If anyone wants me to post the solution, just let me know.
