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)`,

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
`DeltaS _(ArarrC )=S _(C)- S_(A) = 50 e.u.` ....(i)
`DeltaS_(CrarrD) = S_(D) -S_(C) = 30e.u.` ....(ii)
`DeltaS_(B rarrD) = S_(D) - S_(B) = 20 e.u. ` .....(iii)
`DeltaS _(A rarrB)= S_(B) -S_(A) =`Eqn. (i) `+` Eqn. (ii)-Eqn.(iii) `=50 + 30-20= 60` e.u.

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 .

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:
