A) \[{{P}_{1}}>{{P}_{2}}\]
B) \[{{P}_{2}}>{{P}_{1}}\]
C) \[{{P}_{1}}={{P}_{2}}\]
D) \[{{P}_{1}}/\left( {{P}_{1}}+{{P}_{2}} \right)={{P}_{2}}/\left( {{P}_{1}}+{{P}_{2}} \right)\]
Correct Answer: A
Solution :
For equimolar solution, osmotic pressure depends on the value of van?t Hoff?s factor (i) \[\therefore \,\,\,Osmotic\text{ }pressure\propto i\] For \[KN{{O}_{3}}\] (being strong electrolyte), completing ionizes, \[{{i}_{1}}=2\] But for \[C{{H}_{3}}COOH\,,\,\,\,{{i}_{2}}=1\,+\propto \] \[\,\therefore \,\,\,\,\,\,{{i}_{1}}>{{i}_{2}}\,\,\,\,\,But\,\,\,\,\,\,\,{{P}_{1}}<{{i}_{1}}\] \[{{P}_{2}}<{{i}_{2}}~~\,\,\,\therefore \,~~{{P}_{1}}>{{P}_{2}}\]You need to login to perform this action.
