Question

the energy absorbed by molecule a two of a substance is. 4.4 into 10 to the power minus 19 Joule and bond energy per molecule is 4into 10 power minus 19 June the kinetic energy of the molecule for atom will be

Answer 1

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.....
