A minimum energy of 225 kJ/mol is required to break a certain chemical bond in a compound. What is the
longest wavelength of radiation (in nm and angstroms, Å; 1 Å = 10−10 m) necessary to break the bond? In
which region of the electromagnetic spectrum does this radiation lie?

    You want 225,000 J/mol or
    225,000 x (1 mol/6.02E23) = ? J/atom
    Then E = hc/wavelength.
    Substitute and solve for wavelength in meters, convert to A and nm.
