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
