## 5G.15

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

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

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

### 5G.15

for 5G.15 I keep getting -2.7 kj per mol but the answer says -27 kj per mol. Can someone tell me what I'm doing wrong is the answer key wrong.

I'm pretty sure the answer key is wrong because I also got -2.7 kJ/mol and the other people I asked also got -2.7 kJ/mol. Also, in my answer key, someone added a decimal point.

I believe the answer key in the book is incorrect.
