Reversibility and Carnot cycle

    I have two short questions:

    1) Is the Carnot cycle completely reversible?

    2) [tex]\Delta S = 0[/tex] for a reversible process, right?

    Yes, the Carnot cycle is designed as being reversible.

    Yes, it is the Clausius theorem for a reversible cycle. On a particular reversible process, a system can increase o decrease its entropy provided that the surroundings decrease or increase it by the same amount, as the universe entropy will remain constant.
