Entropy is a state function hence. Δ SA arrow B =Δ SA arrow C+Δ SC arrow D+Δ SD arrow B =50 eu +30 eu +(-20 eu )=60 eu

Q. The direct conversion of $A$ to $B$ is difficult, hence it is carried out by the following shown path

Given that $Δ S_{(A \to C)} = 50$ eu
$Δ S_{(C \to D)} = 30$ eu
$Δ S_{(D \to B)} = - 20$ eu
where, eu is entropy unit
Then, $Δ S_{(A \to B)}$ is

+ 100 eu

+ 60eu

-100 eu

-60 eu

Entropy is a state function hence.
$Δ S_{A \to B} = Δ S_{A \to C} + Δ S_{C \to D} + Δ S_{D \to B}$
$= 50 e u + 30 e u + (- 20 e u) = 60 e u$

Q. The direct conversion of A to B is difficult, hence it is carried out by the following shown path Given that ΔS(A→C)​=50 eu ΔS(C→D)​=30 eu ΔS(D→B)​=−20 eu where, eu is entropy unit Then, ΔS(A→B)​ is
