A photon of energy 12 eV can break three...

A photon of energy `12 eV` can break three molecules of `A_2` into atoms which has bond dissociation energy of `4 eV//"molecule"`.
Total energy is conserved and interaction is always one to one between photon and molecule.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Since interaction between a photon and a molecule is always one to one, so a photon of energy `12 eV` can break only one molecule of `A_2` into atoms and remaining `8 eV` energy becomes kinetic energy of atoms.
