The direct conversion of A or B is difficult, hence it is carried out by the following shown path
Given, `DeltaS_(A to C) = 50 eu`, `DeltaS_(C to D) = 30 eu, DeltaS_(B to D) =20 eu`

Where eu is entropy unit, then `DeltaS_(A to B)` is .

A

`+100` eu

B

`+60` eu

C

`-100` eu

D

`-60` eu

Text Solution

Verified by Experts

The correct Answer is:
B
`underset(A)underset(darr)C to underset(B)underset(darr)D`
Given, `DeltaS_(A to C) = 50 eu`
`DeltaS_(C to D) = 30 eu, DeltaS_(B to D) = 20 eu`
Where, eu is entropy unit
Therefore, `DeltaS_(A to C) + DeltaS_(C to D) -DeltaS_(B to D) = 50 + 30-20 = 60` eu

The direct conversion of A to B is difficult. Hence it is carried out by the following shown path: DeltaS(ArarrC)=50e.u.,DeltaS(CrarrD)=30e.u, DeltaS(BrarrD)=20e.u where e.u is entropy unit. Then DeltaS(ArarrB) ,

The direct conversion of A to B is difficult, hence is carried out by the following shown path: Delta(AtoC)=50, DeltaS(CtoD)=30,DeltaS(BtoD)=20 The entropy change for the process A to B is :

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:

The conversion A to B is carried out by the following path : {:(C rarr D),(uarr" "darr),("A B"):} Given : Delta S_((A rarr C))=50 e.u. , Delta S_((C rarr D))=30 e.u., Delta S_((B rarr D))=20 e.u. where w.u. is entropy unit then Delta S_((A rarr B)) is

A process AtoB is difficult to occur directly instead it takes place in the three successive steps. DeltaS(AtoC)=50e.u. DeltaS(CtoD)=30e.u. DeltaS(BtoD)=20e.u. where e.u. is entropy unit. Then the entropy change for the process DeltaS(AtoB) is:
