  According to the Clausius inequality, what is the value of the cyclic integral of δQ/T for an arbitrary thermodynamic cycle operating between thermal reservoirs?

  • AIt is equal to zero for all cycles because entropy is a state function.
  • BIt is equal to zero for a reversible cycle and less than zero for an irreversible cycle.
  • CIt depends exclusively on the total mechanical work produced during the complete cycle.
  • DIt is always strictly positive for real systems.
