H-Cl Bond Energy Explained: ?H Signs Formation & Breakage Dynamics
Chapter 9, Problem 24P(choose chapter or problem)
Define bond energy using the \(\mathrm{H}-\mathrm{Cl}\) bond as an example. When this bond breaks, is energy absorbed or released? Is the accompanying \(\Delta H\) value positive or negative? How do the magnitude and sign of this \(\Delta H\) value relate to the value that accompanies \(\mathrm{H}-\mathrm{Cl}\) bond formation?

How do the magnitude and sign of this \(\Delta H\) value relate to the value that accompanies \(\mathrm{H}-\mathrm{Cl}\) bond formation?
ANSWER:Step 1 of 2
Here we have to define bond energy using the \(\mathrm{H}-\mathrm{Cl}\) bond as an example and have to explain when this bond breaks, energy is absorbed or released, is the accompanying \(\Delta \mathrm{H}\) value positive or negative, how do the magnitude and sign of this \(\Delta \mathrm{H}\) value relate to the value that accompanies \(\mathrm{H}-\mathrm{Cl}\) bond formation.
Bond energy:
Bond energy is defined as the amount of energy required to overcome the force of attraction between \(\mathrm{H}\) atoms and \(\mathrm{Cl}\) atoms in one mole of \(\mathrm{HCl}\) molecules in a gaseous state.
