Question Energy absorbed by each molecule(A2) of a substance is 4.4 * 10raised to power -19 j and bond energy per molecule is 4.0 *10 raised to power -19j .the kinetic energy of the molecule per atom will be?

Solution That will be just the difference between absorbed energy and bond energy divided by 2 as we have 2 atoms after splitting:

$E=(4.4\cdot 10^{-19}-4.0\cdot 10^{-19})/2=0.2\cdot 10^{-19}\,J$
