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
