The direct conversion of `A` to `B` is difficult hence it is carried out by the following shown path `underset(A)underset(uarr)(C)rarrDunderset(B)underset(darr)`
Given,
`DeltaS_((A rarr C)) = 50 eu`
`DeltaS_((C rarr D)) =30 eu`
`DeltaS_((B rarr D)) = 20 eu`
where eu is the entropy unit, then `DeltaS_((A rarr B))` is

A

`+60 e.u.`

B

`+100 e.u.`

C

`-60 e.u.`

D

`-100 e.u.`

Text Solution

Verified by Experts

The correct Answer is:
a
Entropy is a state function `DeltaS_(A to C) +DeltaS_(C to D) = DeltaS_(A to B)`

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 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:

Name the end product in the following series of reaction. CH_(3)COOHoverset(NH_(3))underset(Delta)rarr Aoverset(P_(4)O_(10))underset(Delta)rarr B

a process A rarr D is difficult to occur directly instead it takes place in three successive steps, DeltaS(ArarrB)=40 e.u., DeltaS(BrarrC)=30 e.u., DeltaS(DrarrC)=20 e.u. where e.u. is entropy unit then the entropy change DeltaS for the process (ArarrD) is
