Gold ions form complexes with cyanide ion according to the equation: #"Au"^(+)(aq) + 2 "CN"^(-) -> ["Au"("CN")_2]^(-)#; #K_f = 2xx10^38# What is the standard state free energy for this reaction?
For this you need to know the relationship between the free energy of the reaction (also called the Gibbs Free Energy,
You already have
For thermodynamics, the standard state is always
So now all we do is plug in the numbers:
From the above we see that the
