Answer:
The wavelength of light require to brake an single I-I bond is 7.92 × 10⁻⁷ m
Explanation:
Amount of energy required to break the one mole of iodine-iodine single bond = 151 KJ
amount of energy to break one iodine -iodine bond = (151 KJ/mol )/ 6.02 × 10²³/mol = 2.51 × 10⁻²² KJ
or
2.51 × 10⁻¹⁹ J
Formula:
E = hc / λ
h = planck's constant = 6.626 × 10⁻³⁴ js
c = speed of light = 3 × 10⁸ m/s
λ
= wavelength
Solution:
E = hc / λ
λ = hc / E
λ = (6.626 × 10⁻³⁴ js × 3 × 10⁸ m/s ) / 2.51 × 10⁻¹⁹ J
λ = 19.878 × 10⁻²⁶ j .m / 2.51 × 10⁻¹⁹ J
λ = 7.92 × 10⁻⁷ m
