Reversible process/entropy thermodynamics

[Chronos000]

Homework Statement

For a reversible process, while the net entropy change must be zero, does this mean that the entropy of the system and surroundings can change as long as they amount to zero?

Homework Statement

For a reversible process, while the net entropy change must be zero, does this mean that the entropy of the system and surroundings can change as long as they amount to zero?

Yes. The entropy change of the system or the surroundings can be greater or less than zero in a process. But they cannot sum to less than zero. In a reversible process, they sum to zero.
