How are O.P. of \(6 \%\) urea \(\pi_1\) and \(6 \%\) glucose \(\pi_2\) related to each other :
1 \(\pi_1>\pi_2\)
2 \(\pi_1<\pi_2\)
3 \(\pi_1=\pi_2\)
4 \(\pi_1=\frac{1}{\pi_2}\)
Explanation:
C.P. \(\propto \mathrm{n}_{\mathrm{B}}=\frac{1}{\text { Molar mass }}\) (For same concentrations in percentage or \(\mathrm{g} \mathrm{L}^{-1}\), when soluties do not associate or disociates) Sucrose, \(\frac{1}{342}<\) Glucose,\(\frac{1}{180} \Rightarrow \pi_1>\pi_2\)

0.2 molal aqueous solutions of each of \(\mathrm{NaCl}, \mathrm{BaCl}_2\) and \(\mathrm{AICl}_3\) have boiling points \(T_1, T_2\) and \(T_3\) respectively. Which of the of following is correct :
1 \(\mathrm{T}_1>\mathrm{T}_2>\mathrm{T}_3\)
2 \(T_3>T_2>T_1\)
3 \(T_2>T_1>T_3\)
4 \(T_1>T_3>T_2\)
Explanation:
\(\Delta \mathrm{T}_{\mathrm{b}}=\mathrm{iK}_{\mathrm{b}} \mathrm{m}\) \(\Delta \mathrm{T}_{\mathrm{b}}\) and hence \(\mathrm{T}_{\mathrm{b}} \propto \mathrm{i}\) (for equal values of \(\mathrm{K}_{\mathrm{b}}\) and \(\mathrm{m})\). Hence, \(\mathrm{T}_3>\mathrm{T}_2>\mathrm{T}_1\).
