## 4J.5

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

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

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

### 4J.5

For this question, we are asked to calculate $\Delta H$ delta S and delta G
"write a balanced chemical reaction of NH3" why do they divide everything to only produce 1 Nh3? It is not stated in the question that they only want one mol to be produced.

When they say "of NH3," they mean one NH3.
