The Cl-Cl bond energy is 199 kJ/mol.Therefore the formation of a single bond between atoms
A)should require the absorption of 199 kJ per mole of Cl-Cl formed.
B)should require the absorption of 398 kJ per mole of Cl-Cl formed.
C)should result in the release of 199 kJ per mole of Cl-Cl formed.
D)should result in the release of 398 kJ per mole of Cl-Cl formed.

Question

Quizplus · Accepted Answer

The Cl-Cl bond energy is the amount of energy required to break a mole of Cl-Cl bonds, which is 199 kJ/mol. Therefore, the formation of a single Cl-Cl bond should result in the release of 199 kJ/mol, as the formation of a bond involves the release of energy. Thus, option C is the correct answer.

The Cl-Cl Bond Energy Is 199 KJ/mol
