## Sig Figs Regarding Gibbs Free Energy Equation

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

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

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

### Sig Figs Regarding Gibbs Free Energy Equation

When using the Gibbs equation, do we use the sig figs rule for addition and subtraction or that for multiplication because the equation uses both multiplication and subtraction.
