Calculate the DeltaH for the isothermal ...

Calculate the `DeltaH` for the isothermal reversible expansion of `1` mole of an ideal gas from initial pressure of `0.1 bar` at a constant temperature at `273K`.

Text Solution

Verified by Experts

The correct Answer is:
0
`P_(1)V_(1)=P_(2)V_(2)` or `PV`=const.
(at constant temperature)
Thus, `DeltaH=DeltaU+Delta(PV)`
`implies DeltaH=0`
