How is isothermal irreversible expansion cyclic  and how is delta H=0 for the process?

Expert Answer:

The isothermal irreversible expansion process is an acyclic process because when the gas expands irreversibly then it can not return into its previous state so it is not cyclic. Enthalpy change is zero in the isothermal process because enthalpy is a function of temperature. So when the temperature is constant it is also constant and Enthalpy change=0.
