WebWhen the bonds in ATP are broken new bonds are being formed, for example if ATP is being hydrolyzed to ADP + Pi the pyrophosphate bond between the outer two phosphates is being broken by "adding" a water molecule. The new bonds are lower energy (more stable) than the pyrophosphate bond and so the net effect is a release of energy. WebBond enthalpy (which is also known as bond-dissociation enthalpy, average bond energy, or bond strength) describes the amount of energy stored in a bond between atoms in a molecule. Specifically, it's the energy that … WebCl2 is the diatomic form of chlorine gas, a strong oxidising agent and a greenish-yellow gas.

WebAnswer to Question #98952 in General Chemistry for Brittany Wallace. 1. The enthalpy change for the following reaction is 81.1 kJ. Using bond energies, estimate the H-Cl bond energy in HCl (g). 2. The enthalpy change for the following reaction is -137 kJ. Using bond energies, estimate the C-C bond energy in C2H6 (g). WebXY ( g) X ( g) + Y ( g) DX − Y = ΔH°. For example, the bond energy of the pure covalent H–H bond, ΔH – H, is 436 kJ per mole of H–H bonds broken: H2 ( g) 2H ( g) DH − H = ΔH° = 436kJ. Breaking a bond always require energy to be added to the molecule. Correspondingly, making a bond always releases energy.

WebThe explanation for the correct option: Option (a) Cl2. Bond energy decreases down the group as the size of the atom increases. So, Fluorine is expected to have the highest bond dissociation enthalpy. But chlorine has the highest bonding energy than fluorine because the fluorine atom has a very small size due to which there is a high ... WebNov 16, 2024 · The bond dissociation energy of F2 is less than Cl2 because fluorine has a high electronegativity, resulting in F−F repelling each other and having lesser bond dissociation enthalpy than Cl2 since Cl is less electronegative than F. Another way of saying this is that F2 is a smaller molecule than Cl2.
