The energy absorbed by each molecule ( A 2 ) of a substance is 4.4 × 1 0 − 19 J and bond energy per molecule is 4.0 × 1 0 − 19 J . The kinetic energy of the molecule per atom will be :NEET 2009 (Mains)

KE = 4.4 × 1 0 − 19 − 4.0 × 1 0 − 19 KE / molecule = 0.4 × 1 0 − 19 KE / atom = 2 0.4 × 1 0 − 19 = 2 × 1 0 − 20 J

The energy absorbed by each molecule $(A_{2})$ of a substance is $4.4 \times 1 0^{- 19} J$ and bond energy per molecule is $4.0 \times 1 0^{- 19} J$ . The kinetic energy of the molecule per atom will be :NEET 2009 (Mains)

Options:

Answer:

Solution:

$KE = 4.4 \times 1 0^{- 19} - 4.0 \times 1 0^{- 19} KE / molecule = 0.4 \times 1 0^{- 19} KE / atom = \frac{0.4 \times 1 0 ^{- 19}}{2} = 2 \times 1 0^{- 20} J$
