Five moles of anideal gas expends reversily from a volume of`8dm^(3)`at a temperature of`27^(@)C`Calculate the change in entropy.

A

`70.26JK^(-1)`

B

`82.55JK^(-1)`

C

`95.73JK^(-1)`

D

`107.11JK^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
Entropy change `(DeltaS)=2.303nR "log" (V_(2))/(V_(1))`
`=2.303xx5xx8.314xx"log"(80)/(8)=95.73JK^(-1)`
