Greater is the effective molarity ( i × C), higher the Δ Tf value and lower the freezing point.

Q. Which of the following has been arranged in the increasing order of freezing point?

$0.025 M K N O_{3} < 0.1 M N H_{2} CSN H_{2} < 0.05 M B a C l_{2} < 0.1 M N a Cl$

$0.1 M N a Cl < 0.05 M B a C l_{2} < 0.1 M N H_{2} CSN H_{2} < 0.025 M K N O_{3}$

$0.1 M N H_{2} CSN H_{2} < 0.1 M N a Cl < 0.05 M B a C l_{2} < 0.025 M K N O_{3}$

$0.025 M K N O_{3} < 0.05 M B a C l_{2} < 0.1 M N a Cl < 0.1 M N H_{2} CSN H_{2}$

Greater is the effective molarity ( $i \times C)$ , higher the $Δ T_{f}$ value and lower the freezing point.
