Answer:
2×10^-20 joule ..
Explanation:
Total energy supplied for A2 is given =4.4×10^-19 J
Bond energy is =4×10^-19 J.
so the energy left after breaking the bond is ={4.4-4.0}×10^-19 J...
=0.4×10^-19 J..
therefore kinetic energy per molecule will be = energy left/2
= 0.4/2×10^-19
= 0.2×10^-19 J. OR = 2×10^-20 J.....
