Reversible and irreversible cyclic processes The answer in Arihant's book is given as (b), but wouldn't (c) be correct as well? This is a question of IIT JAM Chemistry.


  A system undergoes two cyclic processes 1 and 2. Process 1 is reversible and Process 2 is irreversible. The correct statement relating to the two processes is
  (a) $\delta S=0$ for Process 1, while $\Delta S\neq0$ for Process 2
  (b) $Q_\text{cyclic}=0$ for Process 1 and $Q_\text{cyclic}\neq0$ for Process 2
  (c) More heat can be converted to work in Process 1 than in Process 2
  (d) More work can be converted to heat in Process 1 than in Process 2
Answer b is incorrect for the reversible Carnot cycle.  The book has given the wrong answer. Answer c is correct if only one cycle of each process is carried out.  You can obviously convert more heat to work if you run process 2 through the same cycle several times, which also counts as a cyclic process.
