Exothermic stronger bonds

Webbreaking a chemical bond absorbs energy. The term bond strength refers to the quantity of energy released when a bond is formed or the energy absorbed when a bond is broken. Hence for a reaction to be exothermic, strong bonds are formed and weak bonds broken while for an endothermic reaction, weak bonds are formed and strong bonds broken. WebApr 1, 2024 · An exothermic reaction involves stronger bonds forming than are broken, it is the formation that releases the energy. Activation energy doesn’t affect this as it only involves the energy that must be overcome during the reaction pathway, not the potential energies of the bonding states before and after. – Withnail Apr 5, 2024 at 21:36

WebA reaction is said to be ________ if the bonds formed during the reaction are stronger than the bonds broken. exothermic All of the statements regarding the symbol "ΔH" are correct except it represents the difference between the energy used in breaking bonds and the energy released in forming bonds in a chemical reaction. WebThe stronger a bond, the greater the energy required to break it. The energy required to break a specific covalent bond in one mole of gaseous molecules is called the bond energy or the bond dissociation energy. The bond energy for a diatomic molecule, D X–Y, is defined as the standard enthalpy change for the endothermic reaction:

WebStronger bonds, such as covalent bonds, require more energy to break and release more energy when formed than weaker bonds, such as hydrogen bonds. Overall, bond formation is an exothermic process, meaning that … WebA reaction is exothermic when a. strong bonds break and weak bonds form. b. weak bonds break and weak bonds form. c. weak bonds break and strong bonds form.

WebInspector_memesau • 1 yr. ago. The reason why any reaction is exothermic is because more energy is released during bond formation than absorbed suring bond breaking. The same applies here.
