One requires 11 eV of energy to dissociate a carbon monoxide molecule into carbon and oxygen atoms. The minimum frequency of the appropriate electromagnetic radiation to achieve the dissociation lies in

  1. microwave region
  2. visible region
  3. ultraviolet region
  4. infrared region

Answers (1)

The answer is the option (c) ultraviolet region

Solution: E = hf

E = required energy to dissociate a carbon monoxide molecule = 11 eV

h = Planck's constant = 6.62 * 10^{-34} j-s

\\f = frequency; f = E/h = 11 * 1.6 * \frac{10^{-19}}{6.62} * 10^{-34} Hz = 2.65 * 10^{15} Hz.

The frequency radiation belongs to the ultraviolet region.
