Q. No.An energy value of \(3.313 \times 10^{-12}\) ergs to break a chemical bond.
What is the wavelength of energy needed to break the bond?
(The speed of light = \(3.00 \times 10^{10} \mathrm {cm/sec};\) Planck's constant = \(6.626 \times 10^{-27}\) erg. sec).
1. \(5.00 \times 10^{-4} \mathrm {cm}\)
2. \(1.00 \times 10^{-5}\mathrm {cm}\)
3. \(2.00 \times 10^{-5} \mathrm {cm}\)
4. \(6.00 \times 10^{-5}\mathrm {cm}\)
