Chapter 17, Problem 17.29E
Interpretation Introduction

Interpretation:

The temperature that is necessary to have twice as many atoms in the ground state as in the first excited state is to be calculated. The temperature that is necessary to have equal populations in the ground state and the second excited state is to be calculated. The temperature that is necessary to have equal populations in the first and second excited states is to be calculated.

Concept introduction:

When energy of an atom increases, then it gets excited from lower energy state to a higher excited state. The number of atoms present in a particular energy state depends upon the temperature and energy of the state. The ratio of atoms in two states is represented as,

NiNk=gigke(ik)/kT

Where,

gi represents the degeneracy of ith microstate.

i represents the energy of ith microstate.

gk represents the degeneracy of kth microstate.

k represents the energy of kth microstate.

k represents the Boltzmann constant with value 1.38×1023J/K.

T represents the temperature (K).

Blurred answer
Students have asked these similar questions
a. What is the eluent used in the column chromatography here (a “silica plug filtration” is essentially a very short column)? b. The spectroscopy of compound 5b is described in the second half of this excerpt, including 1H-NMR and 13C-NMR (which you will learn about in CHEM 2412L), MS (which you will learn about later in CHEM 2411L) and IR. One of the IR signals is at 3530 cm-1. What functional group does this indicate might be present in compound 5b?
Steps and explanations. Also provide, if possible, ways to adress this kind of problems in general.
a. The first three lines of this procedure describe the reaction used to make compound 5b. In the fourth line, hexane and sodium bicarbonate are added. What organic lab technique is being used here?  b. What is the purpose of the Na2SO4?  c. What equipment would you use to “concentrate [a solution] under reduced pressure”?
