## Week 10 Review Question 6

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

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

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

### Week 10 Review Question 6

The answer for this question is found by substituting -RTlnK for ΔG°in ΔG = ΔG° +RTlnQ, and then plugging in values for the variables. This makes sense to me, but I don't understand why I don't get the same answer if I just plug in -37.2 kJ/mol for ΔG°, which was the value found in Question 5.

^^^^ same question, isn't it the same delta G?
