Bond Energy and Reaction Enthalpy
Which of the following statements regarding bond energies and their use in enthalpy calculations is incorrect?
A
Calculating overall reaction enthalpy using bond energies involves subtracting the energy released during bond formation from the energy required to break bonds.
B
The number of bonds broken is determined by both the mole quantity of the substance and the number of individual bonds, contributing to energy absorption.
C
Bond energies are always negative, reflecting that energy is released when bonds form.
D
Bond energy values are positive, and energy is released (exothermic) when bonds form, resulting in a net negative ΔH if sufficient energy is released.
