Match the boiling point with K(b) for x,...

Match the boiling point with `K_(b)` for `x,y` and `z`, if molecular weight of `x,y` and `z` are same.
`{:(,b.pt,,k_(b),),(x,100,,0.68,),(y,27,,0.53,),(z,253,,0.98,):}`

Text Solution

Verified by Experts

The correct Answer is:
`K_(b) (x) = 0.68, K_(b) (y) = 0.53, K_(b) (z) = 0.98`
`K_(b) prop T_(b)^(2)`

Mach the boiling point with K_(b) for x,y and z, if molecular weight of x,y and z are same. {:(,b.pt.,"K"_("b")),(x,100,0.68),(y,27,0.53),(z,253,0.98):}

Match the following if the molecular weights of X,Y and Z are the same.

Match the following if the molar mass of X, Y and Z are the same. {:("solvent",T_b//^@C,K_b//kg" "K mol ^(-1)),(X,127,0.73),(Y,27,0.53),(Z,253,0.98):}

Show that |(0,x,y,z),(-x,0,c,b),(-y,-c,0,a),(-z,-b,-a,0)|=(ax-by+cz)^2

Consider the three solvents of identical molar masses. Match their boiling point with their K_(b) values {:(ul(bar("Solvents" " ""Boiling point" " "K_(b) "values" " "))),(ul(X " " 100^(@)C " " 0.92 " ")),(ul(Y " " 27^(@)C " "0.63" ")),(ul(Z " " 283^(@)C " "0.53 " ")):}

If the points A(x,y+z),B(y,z+x) and "C(z,x+y)" are such that AB=BC ,then x,y,z are in A .P

Show without expanding at any stage that: [x,a,x+a],[y,b,y+b],[z,c,z+c]|=0
