CH4 + 2 Cl2--> CH2Cl2 + 2HCl

Cl-Cl bond energy: 242 kj/mole

1. Calculate the amount of energy (Joules) needed to break a single Cl-Cl bond.

2. Calculate the longest wavelength of light (meters)that can supply the energy per photon necessary to break the Cl-Cl bond.

    242 kJ/mol = 242,000 J/mol
    242,000 J/mol x (1 mol/6.022 x 10^23 molecules) = E for one molecule in joules.

    E = hc/wavelength.
