Problem 16 : A reaction has an equilibrium constant Kc = 0.10 at a certain temperature. Calculate the value of ∆G° for this reaction at the same temperature. (R = 8.314 J/(mol•K))
Solution :

The relationship between ∆G° and Kc is given by the equation: ∆G° = -RT ln(Kc)

To calculate ∆G°, you need to know the temperature (T) at which the equilibrium constant Kc is given.
