**1. Homework Statement**

The equilibrium vapor pressures of liquid gallium are

T(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?

[tex]

Ga(l) \rightarrow Ga(g, 0.1 torr)

[/tex]

at 1427 K.

Heres what I derived so far

[tex]

dG=Vdp

dG=\frac{RT}{p}dp

\Delta G=RTln\frac{p_2}{p_1}

[/tex]

I'm not sure how to get [tex]p_1[/tex] to solve for [tex]\Delta G[/tex]
