How much energy, in joules, is required to break the bond in ONE chlorine molecule? The bond energy of Cl2 is 242.6kJ/mol?
2.426E5 J / 6.02E23
To find the energy required to break the bond in one chlorine molecule, you need to convert the given bond energy from kilojoules per mole (kJ/mol) to joules.
First, let's convert the given bond energy of Cl2 from kJ/mol to J/mol by multiplying it by 1000:
242.6 kJ/mol × 1000 J/kJ = 242,600 J/mol
Now, since we want the energy for one molecule, we need to convert from J/mol to J per molecule. This can be achieved by dividing the value by Avogadro's number, which is approximately 6.022 × 10^23 molecules/mol:
242,600 J/mol ÷ 6.022 × 10^23 molecules/mol = 4.03 × 10^-19 J/molecule
Therefore, the energy required to break the bond in one chlorine molecule is approximately 4.03 × 10^-19 joules.
