Write the relationn between `DeltaS_(sy)&DeltaS_("surr")` when a process reaches equilibrium. What will be the value of `DeltaS_("univ")` ?

Text Solution

Verified by Experts

For a process at equilibrium `DeltaS_("system")+DeltaS_("surr")=0`
But `DeltaS_("sys")+DeltaS_("surr")=DeltaS_("univ")`. So, `DeltaS_("univ")=0`.
