What are the conditions for an ideal solution which obeys Raoult's law over the entire range of concentration ?

Options

A. `Delta_(mix)H = 0,Delta_(mix) V = 0 , P_(Total)=p_(A)^(0)x_(A) + p_(B)^(0)x_(B)`
B. `Delta_(mix)H = +ve,Delta_(mix) V = 0 , P_(Total)=p_(A)^(0)x_(A) + p_(B)^(0)x_(B)`
C. `Delta_(mix)H = 0,Delta_(mix) V = +ve , P_(Total)=p_(A)^(0)x_(A) + p_(B)^(0)x_(B)`
D. `Delta_(mix)H = 0,Delta_(mix) V = 0 , P_(Total)= p_(B)^(0)x_(B)`

Answer

A

Explanation

For an ideal soluton, `Delta H ` and Delta V for mixing should be zero. `P_("Total") =p_(A)+p_(B) ` and `A-A,B-B` and`A-B` interactiions are nearly same.
