Yes, standard conditions assume 298.15 K or 25 degrees Celsius, which one you use in your calculations just depends on the kind that you are doing.

What do you mean by "what kind you're doing"? I would think that it is always in kelvins.

Yes, it would be 298K because T is in Kelvin in the Gibbs free energy equation.

If given degrees Celsius, convert to K.
