The diagram representing the relationship between total spin angular momentum ( S ) and the z-component of spin angular momentum ( S z ) for the electron spin is to be drawn. Concept introduction: Angular momentum is shown by the orbitals when the atom is rotating. The energy of rotation of atom depends upon the quantum number ( l ) but does not depend upon the quantum number ( m l ) as the total angular momentum of the atom is quantized. Similarly the motion of electron is also accompanied by angular momentum.

Question

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NOCI (g) 2NO (g) + Cl2 (g) AGº =41. kJ Now suppose a reaction vessel is filled with 4.50 atm of nitrosyl chloride (NOCI) and 6.38 atm of chlorine (C12) at 212. °C. Answer the following questions about this system: ? rise Under these conditions, will the pressure of NOCI tend to rise or fall? x10 fall Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of NOCI will tend to fall, can that be changed to a tendency to rise by adding NO? yes no If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it. Round your answer to 2 significant digits. 0.035 atm ✓ G 00. 18 Ar

Question

Chapter 16, Problem 16.19E

Interpretation Introduction

Interpretation:

The diagram representing the relationship between total spin angular momentum (S) and the z-component of spin angular momentum (Sz) for the electron spin is to be drawn.

Concept introduction:

Angular momentum is shown by the orbitals when the atom is rotating. The energy of rotation of atom depends upon the quantum number (l) but does not depend upon the quantum number (ml) as the total angular momentum of the atom is quantized. Similarly the motion of electron is also accompanied by angular momentum.
