0The direct conversion of \( A \) to \( B \) is difficult, hence it is carried out as :
\( A \longrightarrow C \longrightarrow D \longrightarrow B \)
Given, \( \Delta S_{(A \rightarrow C)}=50 \mathrm{eU} ; \Delta S_{(C \rightarrow D)}=30 \mathrm{eU} ; \Delta S_{(B \rightarrow D)}=20 \) \( e U \); where \( e U \) is entropy unit. Thus change in entropy in \( (A \rightarrow B) \) is :
(A) \( 100 \mathrm{eU} \)
(B) \( 60 \mathrm{eU} \)
(C) \( -100 \mathrm{eU} \)
(D) \( -60 e U \)
