### Negative Enthalpy

Why do things that fo to a lower energy level happen by themselves?

Spontaneous reactions depend on whether or not the delta G is negative; since the equation for delta G is
deltaH-T(deltaS), then if the enthalpy is positive you can still have a negative delta G (and a spontaneous reaction) if the absolute value of T(deltaS) is greater than the enthalpy change

They do not necessarily happen by themselves since enthalpy is a state function. It depends on the intermediate energy when going from the initial enthalpy to the final enthalpy.
