Among the following, the state function(s) is (are)

Options

  1. Ainternal energy
  2. Birreversible expansion work
  3. Creversible expansion work
  4. Dmolar enthalpy

Correct answer

A. internal energy

Step-by-step solution

State function are internal energy and molar enthalpy. Work is a path dependent function, however in reversible process the path is fixed i.e. between a given initial and final state there is just on reversible path and one work. Hence, reversible work is also a state function.
