Delta G vs. Delta G (degree sign)

How is the delta G and the standard state delta G (with degree sign) differ? Is the standard state delta G constant for a specific rxn while delta G (w/o the degree) could be different?

I think you are right. Delta G depends on specific conditions the reaction is in, but standard delta G is just under standard conditions, which means that standatd delta G will be constant for a reaction.

Remember that standard conditions are 1 atm and 298 K, meaning it's constant.

Just to add on, if there's a º to something, i.e. ∆Gº or ∆Hº or ∆Sº, it always refers to "under standard conditions" so you would already know T = 298 K and P = 1 atm.

It's just the difference between standard conditions and specific conditions for a system.
