If one mole of an ideal gas `(C_(p,m)=(5)/(2)R)` is expanded isothermally at 300 K until it's volume is tripled, then change in entropy of gas is :

A

`-R ` ln 3

B

`R` ln 2

C

`R` in 3

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
3
R ln 3. As entropy is state function and do not depends on path.
