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`

Explanation

Benzene and Naphthalene form an ideal solution at room temperature.
`impliesDeltaH=0`
For mixing of liquids `DeltaS_("system")` is positive. (Entropy increase for mixing).
`DeltaS_("surr")=(-(q_(sys))/T)=0` (Since for ideal solution `DeltaH_("mix")=0)`
