Two moles of an ideal gas expanded isothermally and reversibly from `1L` to `10L` at `300K`. What is the enthalpy change?

A

`11.4`

B

`-11.4`

C

`0`

D

`4.8`

Text Solution

Verified by Experts

The correct Answer is:
c
For `1` mole `DeltaH=DeltaU+PDeltaV`
`=C_(v)=(T_(2)-T_(1))+R(T_(2)-T_(1))`
`DeltaH=(C_(v)+R)DeltaT`
`:' DeltaT=0 :. DeltaH=0`
