Chapter 17, Problem 40E

Consider the evaporation of methanol at 25.0 °C

${\text{CH}}_{\text{3}}\text{OH}\left(l\right)\to {\text{CH}}_{\text{3}}\text{OH}\left(g\right)$

a Find $\Delta G$ at 25.0 °C
b Find $\Delta G$ at 25.0 °C under these nonstandard conditions:

i. PCH₃OH = 150.0 mmHg
ii. PCH₃OH = 100.0 mmHg
iii. PCH₃OH = 10.0 mmHg
c. Explain why methanol spontaneously evaporates in open air at 25.0 °C.
