Question 15.65 Part B

From Part A, I got the equilibrium constant to be .676.

Considering the Standard change in Gibbs Free Energy formula, with a positive K and positive T then the free energy would be negative and thus the reaction would be exothermic. However the answer is endothermic. Why?

Re: Question 15.65 Part B

I believe that the answer is endothermic as in the equation a bond is being made which requires heat whereas if a bond was being broken, the equation would have been exothermic.
