Since, energy has to be supplied to break the bond , so the bond energy for a molecule is always positive. Hence, option (a) is correct.

26 мар. 2022 г. · Pretty sure bond enthalpies are always positive. To break bonds, energy needs to be taken in (endothermic) hence, positive. (negative ...

11 июл. 2023 г. · When a bond is strong, there is a higher bond energy because it takes more energy to break a strong bond. This correlates with bond order and bond length.

5 янв. 2024 г. · Since energy is needed to break the bond, the process is endothermic and thus bond energy is positive.

12 июл. 2023 г. · Energy is always released to make bonds, which is why the enthalpy change for breaking bonds is always positive. Energy is always required to ...

Bond enthalpy is always positive, while bond forming energy is always negative. The answer is A.

For this reason, bond enthalpy values are always positive, and they usually have units of kJ/mol ‍ or kcal/mol ‍ . The higher the bond enthalpy, the more energy ...

14 февр. 2022 г. · Bond enthalpies are always positive because they are the amount of energy required to break chemical bonds. Why is bond enthalpy positive, reaction ... - Laurence Lavelle How can bond enthalpies always be positive? Bond Enthalpies and Signs - CHEMISTRY COMMUNITY Bond Enthalpy - CHEMISTRY COMMUNITY Другие результаты с сайта lavelle.chem.ucla.edu

That is bound to need energy and so bond enthalpies are always positive. When you make a bond, as much energy is given out as you needed to break it, but the ...
