the energy absorbed by each molecule(A 2 ) of a substance is 4.4×10 -19 J and bond energy per molecule is 4.0×10 -19 J the kinetic energy of the molecule per atom will be: 2.2×10 -19 J 2.0×10 -19 J 2.0×10 -20 J 4.0×10 -20 J

That will be just the difference between absorbed energy and
bond energy divided by 2 as we have 2 atoms after splitting:
E = (4.4 · 10^−19 − 4.0 · 10^−19)/2 = 0.2 · 10^−19 J = 2 * 10^-20 J

							Dear Student,
Please find below the solution to your problem.

difference between absorbed energy and bond energy divided by 2
as we have 2 atoms after splitting:
E = (4.4 · 10^−19 − 4.0 · 10^−19)/2
= 0.2 · 10^−19 J
= 2 * 10^-20 J

Thanks and Regards
