A) \[D<C<B<A\]
B) \[D>C<B<A\]
C) \[D<B>A<C\]
D) \[D>A>B>C\]
Correct Answer: C
Solution :
Elevation in boiling point and depression in freezing point, both are the colligative properties, ie, depend only upon the number of particles. In other words, as the number of particles increases, boiling point increases but freezing point decreases. Since, the order of boiling points is \[{{\beta }_{4}}=\frac{1}{dissociation\text{ }constant}\] \[=\frac{1}{4.76\times {{10}^{-14}}}\] The order of freezing point is \[=2.1\times {{10}^{13}}.\] or \[2NO+{{O}_{2}}\rightleftharpoons 2N{{O}_{2}}\]
