Chapter 7, Problem 115CWP

Interpretation Introduction

Interpretation:

Which one of the following system is (are) work done by the surrounding at constant temperature and pressure to be identified.

1. a. ${\text{2SO}}_{\text{2(g)}}+{\text{O}}_{\text{2(g)}}\to {\text{2SO}}_{\text{3(g)}}$
2. b. ${\text{CO}}_{\text{2(s)}}\to {\text{CO}}_{\text{2(g)}}$
3. c. ${\text{4NH}}_{\text{3(g)}}+{\text{7O}}_{\text{2}}\to {\text{4NO}}_{\text{2(g)}}+{\text{6H}}_{\text{2}}{\text{O}}_{\text{(g)}}$
4. d. ${\text{N}}_{\text{2}}{\text{O}}_{\text{4(g)}}\to {\text{2NO}}_{\text{2(g)}}$
5. e. ${\text{CaCO}}_{\text{3(s)}}\to {\text{CaO}}_{\text{(s)}}+{\text{CO}}_{\text{2(g)}}$   

Concept introduction:

Work done on the system by surrounding can be defined as if there is a compression work done on the system by surrounding.
