1.	The direct conversion of `A` to `B` is difficult, hence it is carried out as `A rarr C rarrD rarr B` Given, `DeltaS_((A^rarrC)) = 50 eU,DeltaS_((C^rarrD))=30eU,DeltaS_((BrarrD))=20 eU`, where `eU` is entropy unit. Thus the change in entropy in `(A rarrB)` is:A. `100 eU`B. `60 eU`C. `-100 eU`D. `-60 eU`
Answer» Correct Answer - b `DeltaS_(AtoB)=DeltaS_(AtoC)+DeltaS_(CtoD)+DeltaS_(BtoD)` `50+30-20=60 eU` `(DeltaS_(BtoD)=20, :. DeltaS_(DtoB)=-20 eU)`
