Question
Chapter 4, Problem 4.9CP
Interpretation Introduction
Interpretation:
The reason for no effect on the value of standard enthalpy change of the reaction when temperature of the system increases from 298 to 325 and return to 298 K.
Concept Introduction :
The reversible procedure is an ideal procedure which never happens but an irreversible procedure which is the natural process normally occurs in nature.
Irreversible process is a process whose direction can't be "reversed" by any small change in the system via its surroundings, as a result the system and surroundings are not always in equilibrium
