Question

Consider the boiling of hydrogen iodide. Determine the value of ΔSsurr at 298 K, and predict whether or not the boiling process is spontaneous at this temperature.

HI(l) → HI(g)           ΔH∘∘vap = 21.16 kJ/mol         ΔS∘∘vap = 89.0 J/K⋅⋅mol

Group of answer choices
ΔSsurr = −0.071 J/K⋅⋅mol, boiling of hydrogen iodide is spontaneous
ΔSsurr = 71.0 J/K⋅⋅mol, boiling of hydrogen iodide is spontaneous
It is not possible to calculate ΔSsurr or predict the spontaneity of this reaction without more information. 
ΔSsurr = −71.0 J/K⋅⋅mol, boiling of hydrogen iodide is spontaneous
ΔSsurr = 0.071 J/K⋅⋅mol, boiling of hydrogen iodide is spontaneous
