Question
Chapter 7, Problem 7.3QE
Interpretation Introduction
Interpretation:
The reason for the production of more emission lines than absorption lines in spectra has to be explained.
Concept Introduction:
When the energy such as heat and electric discharge is supplied to the gaseous sample, then the atoms of the sample excited to the higher energy level. These atoms can emit some of energy that is added in a light form, and the pattern of these light is known as spectrum. When these lights appear only at specific wavelength then spectrum is known as line spectrum.

Calculate the free energy change under nonstandard conditions (AGrxn) by using the following relationship:
AGrxn = AGrxn + RTInQ,
AGxn+RTInQ,
where AGxn is the standard free energy change, R is the ideal gas constant, T is the temperature in kelvins, a
