If one mole of an ideal gas `(C_(p.m)=(5)/(2)R)` is expaned isothermally at `300K` until it's volume is tripled , then change in entrop of gas is `R` in 3 if above expansion is carried out freely `(P_(ext)=0)`, then find `DeltaS`?

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.
