Equilibrium Constant and Temperature

Postby annabel 2A » Sat Mar 09, 2019 3:43 pm

When asked to calculate the equilibrium constant from deltaG°=-RTlnK, will we always be told what temperature to calculate it at?

For example, on Karen's Gibbs Free Energy worksheet #1d, how do we know what temperature to calculate the equilibrium constant at?

The assumption for delta G standard is that the temperature is at 25 degrees C or 298 K.

i believe standard temperature is 25 C. /298 K, and the question may also state it
