In a closed system, it is possible to measure the combination of enthalpy and entropy into a single value, which is called Gibbs free energy, detoned with the letter G. The formula to calcula Gibbs free energy is:

ΔG = ΔH - TΔS

Where:

ΔG = is the gibbs free energy

ΔH = is the change in enthalpy

T = temperature in Kelvin

ΔS = change in entropy

We have as values:

ΔH = 31.0 kJ/mol

T = 294K

ΔS = 93.0 J/molK, we need to convert into kJ, therefore it will be 0.093 kJ/molK

Now we add these values into our formula

ΔG = 31.0 - 294*0.093

ΔG = 3.66 kJ
