## HW Problem 11.77b

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

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

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

### HW Problem 11.77b

Could someone please explain to me how to do homework problem 11.77b, "Predict whether each of the following equilibria will shift toward products or reactants with a temperature increase: X2(g)---->2X(g), where X is a halogen."
Thank you.

Hey Mike,
So generally when we increase the temperature there is a shift will be a shift towards the reactants in an exothermic reaction, and a shift towards the products in an endothermic reaction. With X2(g)-->2X(g), we must evidently break the bond between X--X, which requires an endothermic process. As a result, this reaction with favor the products.

Hope this helps.
