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

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

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

### Lavelle's Review Slides

On slide 5, we are told to calculate the partial pressure in bar so we use lnk=deltaG/-RT

I understood what we were doing when we got k to equal 10. The next step was setting k to equal the concentrations of product over the concentration of reactants giving us 10=2x/x^2. How do we get x to equal 0.2 bar?

If you algebraically solve for x, you can cancel out x on both sides of the division equation on the right side, leaving you with 10 = 2/x, where x would equal 0.2
