A solvent is being considered for an experiment with ΔvapS°=112.9 J K−1 mol−1 and ΔvapH°=38.0 kJ mol−1.

The experiment is to be run at 75°C and the solvent must not boil.
Based on the entropy change of the universe associated with the vaporization reaction, would this solvent be suitable and why or why not?

Select one:

The solvent would not be suitable because ΔSuniv<0.

The solvent would be suitable because ΔSuniv<0.

The solvent would not be suitable because ΔSuniv>0.

The solvent would be suitable because ΔSuniv>0.
