Chapter 7, Problem 59E

Interpretation Introduction

Interpretation:

The maximum amount (in moles) of ${\text{CH}}_{\text{3}}\text{X}$ that breaks apart is to be calculated.

Concept introduction: If an atom absorbs energy then this atom gets excited from the lower energy orbital to the higher energy orbital. This state of an atom is termed as excited state. The energy absorbed by an atom is calculated by the Planck’s equation. This equation states that energy is inversely proportional to the wavelength and the number of photons absorbed as,
$E=\frac{nhc}{\lambda }$

The quantum yield $\left(\varphi \right)$ of light-induced chemical reaction is given as,
$\varphi =\frac{\text{Number}\text{of}\text{molecules}}{\text{Number}\text{of}\text{photons}\text{absorbed}}$

To determine: The maximum amount (in moles) of ${\text{CH}}_{\text{3}}\text{X}$ that breaks apart.
