In a chemical reaction energy is released
WebApr 9, 2024 · If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants, because they gave off some free energy during the reaction. Webcalculating energy released in nuclear reactions The binding energy is equal to the amount of energy released in forming the nucleus, and can be calculated using: E=(\Delta m) c^2
