Question
The direct conversion of A to B is difficult, hence it is carried out by the following shown path:
Given ᐃS(A → C) = 50 e.u.
ᐃS(C → D) = 30 e.u.
ᐃS(B → D) = 20 e.u.
where e.u. is entropy unit then ᐃS(A → B) is
Given ᐃS(A → C) = 50 e.u.
ᐃS(C → D) = 30 e.u.
ᐃS(B → D) = 20 e.u.
where e.u. is entropy unit then ᐃS(A → B) is
Options
A.+ 100 e.u.
B.+ 60 e.u.
C.- 100 e.u.
D.- 60 e.u.
Solution
ᐃS(A → B) = ᐃS(A → C) + ᐃS(C → D) - ᐃS(B → D) = 50 + 30 - 20
