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

Options

A. `Delta G` is positive
B. `Delta S_("system")` is positive
C. `Delta S_("surrounding") = 0 `
D. `DeltaH = 0`

Answer

B, C, D

Explanation

For an ideal solution.
(i) `Delta G lt 0` for mixing .
(ii) `Delta S_("system") gt 0` because disorder incrase.
(iii) `Delta S_("surr") = 0 `, no heat is exchange in case of ideal solution .
(iv) `Delta H_("mixing") = 0`
Therefore , statements b,c and d are correct.
