The reduction in the freezing point of a solution is _____ to molal concentration.

inversely proportional
directly proportional
not related
unimportant

Respuesta :

B would be your answer

Answer : The correct option is, directly proportional

Explanation :

Formula used for lowering in freezing point :

[tex]\Delta T_f=k_f\times m\\\\T^o_f-T_f=k_f\times m[/tex]

where,

[tex]\DeltaT_f[/tex] = change in freezing point

[tex]T^o_f[/tex] = freezing point of pure solvent

[tex]T_f[/tex] = freezing point of solution

[tex]k_f[/tex] = freezing point constant

m = molality

From this we conclude that the reduction in the freezing point of a solution is directly proportional to the molal concentration.

Hence, the correct option is, directly proportional
