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 e.u.

B

+ 60 e.u.

C

– 100 e.u.

D

– 60 e.u.

Text Solution

Verified by Experts

The correct Answer is:
B
`S_C - S_A = 50 e.u.`
`S_D - S_C = 30 e.u.`
`S_B - S_D = -20 e.u.`
On addition of these equations we get
`S_B - S_A = 60 e.u.`
`Delta S_(A to B) = 60 e.u.`

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:
