A gas (C(v,m)=(5)/(2)R) behaving ideally...

A gas `(C_(v,m)=(5)/(2)R)` behaving ideally was allowed to expand reversibly and adiabatically from 1 litre to 32 litre. Its initial temperature was `327^(@)C`. The molar enthalpy change (in J/mol) for the process is:

Text Solution

Verified by Experts

The correct Answer is:
`-3150`
`T_(2)=600(1/25)^(2//5)=150K`
`DeltaH_(m)=(7R)/(2)(150-600)=-3150` Cal
