Homework Statement
The equilibrium vapor pressures of liquid gallium areT(K) 1302 1427 1623p(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]
