{I_2}

molecule dissociates into atoms after absorbing light of 4500 A°. If one quantum of energy is absorbed by each molecule, the KE of iodine atoms will be (BE of

{\mathrm{I}_2} = 240\,\,kJ/mol

)

View answer and explanation

Correct option: B

0.216 \times {10^{ - 19}}J

Option B (

0.216 \times {10^{ - 19}}J

) is correct because it represents the kinetic energy of the iodine atoms calculated by subtracting the bond energy from the energy of the absorbed photon.
