Energy in chemical reaction

WebA chemical reaction occurs when you no longer have the same substance or substances, but have some new substance or substances. Changing the state (such as boiling, freezing, melting, or grinding up) still leaves you with the same substance or … WebEndergonic reaction. An endergonic reaction (such as photosynthesis) is a reaction that requires energy to be driven. Endergonic means "absorbing energy in the form of work." The activation energy for the reaction is typically larger than the overall energy of the exergonic reaction (1). Endergonic reactions are nonspontaneous.
