In my textbook it says "CHemical reactions that resease energy often occur on their own, or spontaneously. Chemical reactions that absorb energy will not occur without a source of energy" Can you please explain this to me. I have a test tomorrow and its just not clicking! Thanks so so much!!

Thank you for the opportunity to help you with your question!

Lower thermodynamic states are considered as the most stable. Therefore if a reaction is exothermic it releases energy spontaneously as it's going to a more stable state.

To get the reaction to a higher thermodynamic state (which is unstable) it needs energy by an energy source.

Please let me know if you need any clarification. I'm always happy to answer your questions.

Do you have an idea about the Gibb's free energy equation?
