Question:

For a process to be at equilibrium, it is necessary that

ΔSsys = 0 and ΔSsurr = 0.

ΔSsys = ΔSsurr.

ΔSsys = 0.

ΔSsys = -ΔSsurr


Answers

Ans : ΔSsys = -ΔSsurr

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.
