What is the difference between ∆G and ∆G°?

∆G° is for fixed temperatures and does not depend on how the composition of the reaction changes as the reaction proceeds
∆G will depend on the composition of the reaction mixture and thus changes as the reaction proceeds

is the change in free energy under standard conditions (25celcius and 1atm) while is the change in free energy under varying temp and pressure conditions. If you're calculating , your and also need to be under standard conditions.

DeltaG: is the change in free energy under a different temperatures and pressure conditions.
DeltaGnaut: is standardized conditions for pressure (1 ATM) and temperture (25 degree celcius/298 Kelvins)
