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?
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.
