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. `-100eu`D. `-60 eu` |

Answer» `DeltaS_((A rarr B)) = DeltaS_((A rarr C)) +DeltaS_((C rarr D)) +DeltaS_((D rarr B))` `= 50 +30 - 20 = 60 eu` |
