## Midterm 2014 Question 6

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

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

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

### Midterm 2014 Question 6

K=e^13.2 is what the CR does, but when I do it, I use the full number e^13.20417583... which varies my answer from the given, 540365, to 542626.

This is a fairly large difference and the final answer is worth 4 pts. Would we get points for doing it either way? CR or round at end way.
