$\Delta G^{\circ}= \Delta H^{\circ} - T \Delta S^{\circ}$

$\Delta G^{\circ}= -RT\ln K$

$\Delta G^{\circ}= \sum \Delta G_{f}^{\circ}(products) - \sum \Delta G_{f}^{\circ}(reactants)$

### Chapter 11 #17

For some reason, I am getting -2.7 kJ/mol for the answer to the problem, but the solutions manual says -27 kJ/mol. My calculations seem to be the same as in the solutions manual, so I was wondering if there's any conversions or anything I'm missing here?

I got this too. I think it's a mistake in the answer key

I also got -2.7 kJ/mol! I think you are right and the answer key has an error in it!
