## 2011 midterm Q6 B

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

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

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

### 2011 midterm Q6 B

When writing the final balanced equation, why did we have to multiply 2 to both Rb and Rb+? is it because of the electrons when you put them together?

### Re: 2011 midterm Q6 B

yes you multiply two to Rb because you have to balance the charges of the electrons from F2+2e--->2F, so that the electrons cancel out and you are left with a balanced equationl of F2+2Rb--->2F- + 2Rb+
