Benzene and naphthalene form an ideal solution at room temperature. For this process,the true statement(s) is (are)

Options

A. `DeltaG` is positive
B. `DeltaS_(system)` is positive
C. `DeltaS_("surroundings") = 0`
D. `DeltaH = 0`

Answer

B, C, D

Explanation

For an ideal solution,
(a) `DeltaG lt 0` for mixing.Hence(a) is not correct.
`DeltaS_(system)` is +ve because disorder increases.
(c) `DeltaS_(surr) = 0` because no heat is exchanged in case of ideal solution.
`DeltaH_(mix) = 0` for an ideal solution.
