The formula `DeltaS=q_(rev)/T` can be isothermal irreversble expansion or not ?

Text Solution

Verified by Experts

Yes, can be used.
For reversible and irreversible isothermal expansion taking place inbetween same `Pand V,Delta S_("reversible")` becomes equal to `DeltaS_("irreversible")` because entropy is a state function.
