Answer:
ΔG is the change in free energy.
Explanation:
The expression for the standard change in free energy is:
[tex]\Delta G=\Delta H-T\times \Delta S[/tex]
Where,
[tex]\Delta G[/tex] is the change in the Gibbs free energy.
T is the absolute temperature. (T in kelvins)
[tex]\Delta H[/tex] is the enthalpy change of the reaction.
[tex]\Delta S[/tex] is the change in entropy.
Hence, the correct option is - ΔG is the change in free energy.
