The direct conversion of A to B is difficult. Hence, it is carried out by the following shown path `:` `DeltaS_((A rarr C)) =50 e.u., ` `DeltaS _((C rarr D)) = 30 e.u. ` `DeltaS_((BrarrD)) = 20 e.u.` where e.u. is entropy unit, then `DeltaS _((A rarr B )) ` isA. `+ 100 e.u. `B. ``+60 e.u. `C. `- 100 e.u. `D. ` - 60 e.u. ` |

Answer» Correct Answer - 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. |
