## Problem 9.69

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

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

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

### Problem 9.69

For the problem 9.69, do you just multiply the deltaG of the NADH reaction by 3 and divide it by the delta G of the reaction for ATP?

### Re: Problem 9.69

You multiply delta G of the NADH reaction and the formation of H2O both by 3 and divide the sum by the delta G of the reaction for ATP. Note that e- form in the NADH reaction and you have to balance that using the H2O reaction.
