Question: entropy is state function. At reversible process, deltaS(universe)=0 but in irreversible process deltaS(universe)>0. what does it happened? isn't is be zero as same as reversible

entropy is state function.

At reversible process, deltaS(universe)=0 but in irreversible process deltaS(universe)>0.

what does it happened? isn't is be zero as same as reversible process?
