The magnitude of enthalpy changes for irreversible adiabiatic expansion of a gas from 1 L to 2L is DeltaH_(1) and for reversible adiabatic expansion for the same expansion is DeltaH_(2). Then :

The magnitude of enthalpy changes for irreversible adiabiatic expansio

1.	The magnitude of enthalpy changes for irreversible adiabiatic expansion of a gas from 1 L to 2L is DeltaH_(1) and for reversible adiabatic expansion for the same expansion is DeltaH_(2). Then :
Answer» `DeltaH_(1)gtDeltaH_(2)` `DeltaH_(1)ltDeltaH_(2)` `DeltaH_(1)ltDeltaH_(2)`, enthalapy being a state FUNCTION `DeltaH_(1)=DeltaE_(1)`, and `DeltaH_(2)=DeltaE_(2)` Where `DeltaE_(1) "and" DeltaE_(2)` are magnitudes changes in internal energy of gas in THREE expansions respectively . Answer :B
