Chapter 21.2, Problem 1PPA

Interpretation Introduction

Interpretation: The wavelength required to break the given molecule with given bond dissociation energy data should be determined.

Concept Introduction:

Bond Dissociation Energy: The minimum energy required to break a bond between two atoms present in the molecule is called bond dissociation energy.

Energy: The energy is conversed property since it can neither be created nor be destroyed but can be transformed. The energy of the photon is obtained by using the following relation

$\begin{array}{l}\text{E}\text{=}\text{hν}\\ \text{h}\to \text{Planck's constant = 6}\text{.63}\times {\text{10}}^{\text{-34}}\text{J}\text{.s}\\ \text{ν}\to \text{frequency}\text{of}\text{the}\text{photon}\end{array}$

Wavelength: The distance between the two continuous maximum displacements present in wave or the two continuous minimum displacements present in a wave exhibited by the photons is called wavelength. The wavelength of the photon is inversely proportional to its frequency. The relationship between them is given by the following formula,

$\text{(wavelength)λ}\text{=}\frac{\text{(velocity of light)c}}{\text{(frequency)ν}}$

Frequency: It denotes the number of waves passes in given amount of time.

The wavelength of photon required to dissociate the given ozone molecule using given energy data.
