The ΔGo for the change from liquid to gaseous water is positive... non-spontaneous. However, we all know that liquid water evaporates easily. This is because:
A) the temperature difference (100 --> 25) is responsible
B) the non-standard concentration of the product is responsible
C) the enthalpy change is different in the 2nd case
D) none of the above
