5 янв. 2024 г. · Breaking a chemical or nuclear bond takes energy, and bond formation releases energy. It is why binding energies are negative. How can we determine if a reaction is endothermic or exothermic ... Why are bond breaking processes endothermic (absorb energy) and ... Why are many bond enthalpies described as averages? - Quora If a chemical bond has energy and we need the same ... - Quora Другие результаты с сайта www.quora.com

29 сент. 2024 г. · The change in energy is negative since the products have less energy than the reactants. Therefore, an exothermic reaction has a negative ΔH ...

26 мар. 2022 г. · To break bonds, energy needs to be taken in (endothermic) hence, positive. (negative enthalpies are for FORMING bonds, energy is released). Confusion about ATP bond breaking vs Exothermic/Endothermic. Is ... Is bond formation endothermic or exothermic? Pulling my hair out ... Why does bond-breaking require energy if catabolic reactions ... Другие результаты с сайта www.reddit.com

Energy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process.

11 июл. 2023 г. · Energy is released to generate bonds, which is why the enthalpy change for breaking bonds is positive. Energy is required to break bonds.

So, the given statement "Breaking a chemical bond has a negative enthalpy change" is false.

It is the energy required to break a bond. As energy has to be supplied for the breakage of a bond, the bond energy of a molecule is always positive.

To determine how much energy will be released when we form a new bond rather than break it, we simply make the bond enthalpy value negative. Because bond ...

Generally, a positive change in enthalpy is required to break a bond, while a negative change in enthalpy is accompanied by the formation of a bond. In other ...
