The magnitudes of enthalpy changes for irreversible adiabatic expansion of a gas from 1L to 2L is ∆H1 and for reversible adiabatic expansion for the same expansion is ∆H2. Then
- ∆H1 > ∆H2
- ∆H1 < ∆H2
- ∆H1 = ∆H2, enthalpy being a state function
- ∆H1 = ∆E1 & ∆H2 = ∆E2 where ∆E1 & ∆E2 are
magnitudes of change in internal energy of gas inthese expansions respectively.
Answer
(B) ∆ H 1 ∆ H 2
