What is entropy and in what units is it expressed ? Discuss the physical significance of entropy.

A

`JK^(-1) "mol"^(-1)`

B

`J "mol"^(-1)`

C

`J^(-1) K^(-1) "mol"^(-1)`

D

`JK "mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Entropy change equal to change in heat per degree. `DeltaS=(q)/(T)`
q=required heat per mol
T=constant absolute temperature
Thus unit of entropy is `KJ^(-1) "mol"^(-1)`
