If increase in boiling point of 1 molal glucose solution is 2K increase in freezing point of 2 molal glucose solution is also 2K. Then state the relationship of K_(b) and K_(f).

Answer»

`K_(B)=1.5 K_(F)`
`K_(b)=0.5 K_(f)`
`K_(b)=2K_(f)`
`K_(b)=K_(f)`

SOLUTION :`(Delta T_(b))/(Delta T_(f))=(i XX m xx K_(b))/(i xx m xx K_(f))`
`therefore (2)/(2)=(1xx1xx K_(b))/(1xx2xx K_(f))`
`therefore K_(b)=2K_(f)`
