## Nonlabile and Inert substances

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

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

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

### Nonlabile and Inert substances

I understand that nonlabile and inert substances are substances that are unstable but survive for long periods, but can someone explain to me why and how they're able to survive for a long time?

They can be thermodynamically unstable yet kinetically very stable, which just means the reaction rate of the substance changing is VERY slow (even though it is happening)
