One mole of an ideal gas at `25^(@)C` is subjected to expand reversible ten times of its intial volume. The change in entropy of expansion is

A

`19.15JK^(-1)mol^(-1)`

B

`16.15JK^(-1)mol^(-1)`

C

`22.15JK^(-1)mol^(-1)`

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaS(q)/(T)=(2.303nRT)/(T)"log"(V_(2))/(V_(1))`
`=2.303xx1xx8.314log10`
`=19.15JK^(-1)mol^(-1)`
