Reversible and Irreversible Processes

According to the entropy theorem, entropy of an isolated system can never decrease and will remain constant only when the process is reversible.

Why is entropy of reversible process always zero

In a reversible process:

For a reversible process at equilibrium, the change in entropy may be expressed as:

In a reversible process, the entropy of a system
