Answer:

ΔG = -145kJ/mol

Explanation:

To solve this question we must use the change in Gibbs free energy:

ΔG = ΔH - TΔS

Where ΔG is change in Gibbs free energy = ?

ΔH is enthalpy change = +35kJ/mol

T is absolute temperature = 120.0K

And ΔS is change in entropy = 1.50kJ/molK

Replacing:

ΔG = 35kJ/mol - 120.0K*1.50kJ/molK

ΔG = 35kJ/mol - 180kJ/mol

ΔG = -145kJ/mol
