Solution

(A) $C_{2} H_{5} O H + H_{2} O$ forms azeotropic mixture at a particular composition. It is a non ideal solution and shows positive deviation from Raoult's law.
(B) $C_{2} H_{5} B r + C_{2} H_{5} I$ forms an ideal solution and obeys Raoult's law.
(C) $P_{A} = P_{A}^{o} χ_{A}$ forms an ideal solution and obeys Raoult's law.
(D) $H_{2} O + H_{2} S O_{4}$ forms azeotropic mixture at a particular composition. It is a non ideal solution and shows negative deviation from Raoult's law.
