Relating Gibbs Free Energy to Equilibrium Constants I am having some trouble relating these two concepts. I know that if K=1 then delta g is zero, and that we can interpret signs and magnitudes. However, i am having trouble determining required temparature based on given aimed K, and standart Gibbs free energy of a reaction.
Here is the kind of problem that i have trouble with:
To solve this problem, you suppose that $\Delta$$H°$  and $\Delta$$S°$ do not change with temperature. You calculate $\Delta$$G°$ by two approaches : $1)$ - $RT$ ln $K_p$, and $2)$ $\Delta$$H°$ - $T\Delta$$S°$. Then $T$ can be easily obtained.
