upper atmosphere chloromethane can be decomposed by light according to the reaction:CH3Cl -> CH3(g) + Cl(g)The energy required for this reaction is 428 kJ mol–1. If each molecule of chloromethane is decomposed by one photon, what is the maximum wavelength that photon can have?

  • chemistry -

    428 kJ/mol x (1 mol/6.022E23 atoms) = ? kJ/atom. Then convert to J/atom.
    Then E = hc/wavelength. Suvbstitute for E, h, and c and calculate wavelength.
