How do you know what temperature to use for delta G when it’s not given in the question?

The standard temperature used is 298k.

Standard temperature is 25 degrees celcius, however for Gibbs free energy we always use Kelvin so it is 273+25 which is 298 K

Sometimes, if given enough values, you may have the use the equation PV=nRT to solve for temperature.

If the temperature is not given try the ideal gas law, however, if that isn't possible, then use k=298.

When it's not given, it is usually suggested to be 298K.
