The standard molar entropy for a monoatomic perfect gas for the translation motion in three dimensions is expressed as shown below.
(ii)
Interpretation:
The standard molar entropy of gaseous xenon at
Concept introduction:
Entropy is a thermodynamic property which shows the randomness or disorder of the atoms within the system. The randomness of the molecules increases when solid is melted and liquid is converted into the vapor state. As in vapor state particles move freely because they are at larger distances from each other.
The standard molar entropy for a monoatomic perfect gas for the translation motion in three dimensions is expressed as shown below.
