Options

A. (ii) and (iv) only
B. (i) and (iii) only
C. (ii),(iii) and (iv) only
D. all of these

Answer

C

Explanation

For an ideal solution,
(i)`DeltaG` lt 0 , for mixing
(ii)`DeltaS_"system"` gt 0 , because disorder increases
(iii)`DeltaS_"surr"` =0 , no heat is exchanged in case of ideal solution.
(iv)`DeltaH_"mix"=0`
