9.63 Positive delta G

Postby Josephine Lu 4L » Tue Feb 19, 2019 6:23 pm

Why are compounds with a positive free energy of formation (delta G) unstable?

Hi! A negative dG of formation means that the G of reactants is greater than the G of products, so if free energy decreases, the end product is more stable. Lower energy means more stability.

For even more clarification, this would mean that the more free energy that the reaction has, the less stable it will be in general. More energy means less stability.

A positive delta G indicates that the reaction is nonspontaneous, or nonfavorable.
