When calculating standard free energy, is T=0K or 298K (25 degrees Celcius)?

The standard state is 298 K or 25 degrees C.

Temperature is not a condition of standard state but 298 K is usually used when standard state values are given. Temperature can be any value in a standard state condition. If the question is in STP(standard temperature and pressure), the temperature is 273k, but this is different from standard state.
