Answer:

The correct answer is option E.

Explanation:

The Gibbs free energy is given by expression:

ΔG = ΔH - TΔS

ΔH = Enthalpy change of the reaction

T = Temperature of the reaction

ΔS = Entropy change

We have :

ΔH = -720.5 kJ/mol =  -720500 J/mol (1 kJ = 1000 J)

ΔS = -263.7 J/K

T = 141.0°C = 414.15 K

\Delta G = -720500 J/mol - (414.15 K\times (-263.7 J/K))

= -611,288.64 J/mol = -611.28 kJ/mol\approx -611.3 kJ/mol

The Gibb's free energy of the given reaction at 141.0°C is -611.3 kJ/mol.
