Correct Answer - A::B::C::D
`S_(200(0)) = underset(0)overset(200)int (C_(p) dT)/(T) =7 J"mol"^(-1)K^(-1)`
`S_(200(f))=7 + (7500)/(200) =44.5 J "mol"^(-1)K^(-1)`
`S_(300(f)) = 44.5 + underset(200)overset(300)int (C_(p) dT)/(T)=44.5 + 60 "In" (300)/(200) + 1.6= 70.43 J "mol"^(-1)K^(-1)`
`S_(300(g)) = 70.43 + (30000)/(300) = 170.43 J "mol"^(-1) K^(-1)`
`S_(800(g)) = 170.43 "In" 50 "In" (600)/(300)=205.09 JK^(-1)"mol"^(-1)`
