## Equilibrium Equation

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

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

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

### Equilibrium Equation

In the equation delta G(r)= -RT ln(k)
what does k represent and is it the same as Q?

### Re: Equilibrium Equation

Q is when the concentrations/partial pressures change in a system. You use Q to compare to K to see which way the reaction shifts
