If one mole of an ideal gas Cp = 5/2 R i...

If one mole of an ideal gas `C_p = 5/2 R` is expanded isothermally at 300 k until it's volume is tripled., if expansion is carried out freely `(P_(ext)=0), then DeltaS is :`

A

zero

B

infinity

C

`R ln 3`

D

None

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaS` will be same because entropy is a state function.
