The work done in erge for the reversible expansion of 1 mole of an ideal gas from a volume of 10 litres to 20 litres at `25^(@)C` is

A

`2.303xx298xx0.082log2`

B

`-298xx10^(7)xx8.31xx2.303log2`

C

`2.303xx298xx0.082log0.5`

D

`2.303xx298xx2log2`

Text Solution

Verified by Experts

The correct Answer is:
D
`w=-2.303nRT` log `(V_(2))/(V_(1))`
`=-2.303xx1xx8.31xx10^(7)xx298` log `(20)/(10)`
`=-298xx10^(7)xx8.31xx2.303` log `2`
