Determine the value of ΔSsurr at 227 K, and predict whether or not the reaction is spontaneous at this temperature.
A(g) + 2B(g) → 2C(g) ΔH∘rxn = 21.16 kJ/mol ΔS∘rxn = −12.3 J/K⋅mol
Group of answer choices
It is not possible to calculate ΔSsurr or predict the spontaneity of this reaction without more information.
ΔSsurr = −93.2 J/K⋅mol, nonspontaneous.
ΔSsurr = 93.2 J/K⋅mol, spontaneous.
ΔSsurr = 0.0932 J/K⋅mol, nonspontaneous.
ΔSsurr = −0.0932 J/K⋅mol, spontaneous.
