Explanation:
Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.
Vapor pressure is inversely proportional to the number of solute particles. Hence, more will be the solute particles lower will be the vapor pressure and vice-versa.
(a) [tex]KClO_{4} \rightarrow K^{+} + ClO^{-}_{4}[/tex]
It dissociates to give two particles.
(b) [tex]Ca(ClO_{4})_{2} \rightarrow Ca^{2+} + 2ClO^{-}_{4}[/tex]
Total number of particles it give upon dissociation are 1 + 2 = 3. Hence, it gives 3 particles.
(c) [tex]Al(ClO_{4})_{3} \rightarrow Al^{3+} + 3ClO^{-}_{4}[/tex]
Total number of particles it give upon dissociation are 1 + 3 = 4. Hence, it gives 4 particles.
(d) Surcose being a cobvalent compound doe not dissociate into ions. Therefore, there will be only 1 particle is present.
(e) [tex]NaCl \rightarrow Na^{+} + Cl^{-}[/tex]
Total number of particles it give upon dissociation are 1 + 1 = 2. Hence, it gives 2 particles.
