Chapter 21.1, Problem 1PPC

Interpretation Introduction

Interpretation:

The graph that represents the best relationship between the wavelength of light and maximum bond enthalpy is to be identified.

Concept Introduction:

The equation relating energy and wavelength is as follows:

$\begin{array}{c}E=\text{h}\upsilon \\ =\frac{\text{h}c}{\lambda }.\end{array}$

Here, $E$ stands for energy/enthalpy (in kilo joules), h is the Planck’s constant, $\upsilon$ is the frequency ${\text{(s}}^{-1})\text{ per second}$, $c$ is the velocity of light $(\text{3}\times {\text{10}}^8{\text{m s}}^{-1})\text{ meter per second}$, $\lambda$ is the wavelength (nm) nanometer.

Greater the energy, larger is its frequency and shorter its wavelength.
