Answer 1

Answer #1

Ans : ΔS_sys = -ΔS_surr

For a process to be at equillibrium , the entropy change of the system must be equal and opposite to the entropy change of the surroundings.

The change in entropy of system and change in entropy of surroundings add to the change in entropy of the universe , which is equal to zero for an ideal reversible process.
