Iodine molecule dissociates into atoms after absorbing light of 450 $$\text{nm}$$. If one quantum of radiation is absorbed by each molecule, calculate the kinetic energy of each iodine atom.

If it can be written as $$a \times 10^b \text{ J}$$ where $$0 \leq a <10$$, find the value of $$\lfloor a \rfloor |b|$$.

Details and Assumptions

$$c= 3.0 \times 10^{8} \text{ m/s} \\ h = 6.63 \times 10^{-34} \text{ Js} \\ 1 \text{ mol}= 6.02 \times 10^{23} \text{ entities} \\ \text{Bond energy of }\ce{I_2}= 240 \text{ kJ mol}^{-1}$$
