Question:

Among the following, the state function(s) is(are): Irreversible expansion work, Internal energy, Reversible expansion work, Molar enthalpy

Internal energy

Molar enthalpy

Irreversible expansion work

Reversible expansion work

Solution:

Among the following, the state functions are internal energy and molar enthalpy. The path functions are irreversible expansion work and reversible expansion work. The value of the state function depends on the initial and final state of the system. It is independent of the path followed. The value of the path function depends on the path followed.
