Match the following if moleculat weight of X, Y and Z are same {:(,"B.Pt.",K_(b)),("X",100,0.68),("Y",27,0.53),("Z",253,0.98):}

Answer»

Solution :`K_(b)=(RT_(b)^(2))/(1000l_(V))=(RT_(b)^(2)M)/(1000DeltaH_(v))=(RT_(b)M)/(1000DeltaS_(v))(becauseDeltaS_(v)=(DeltaH_(v))/(T_(b)))`
Where `DeltaS_(v)` is entropyo f vaporisation at the boiling point `T_(b)`.
Entropy of vaporisation, `DeltaS_(v)=S_(v)-S_(L)` is almost constant. This is because though entropy of liquid `(S_(l))` VARIES from liquid to liquid but entropy of vapour `(S_(v))` is ABNORMALLY higher. As M and R are also constant, hence `K_(b) prop T_(b)`. Thus, the values reported in the table are in the correct order.

Match the following if molecular masses of X, Y, Z are same

Answer»

SOLUTION :`K_(b) = (RT_(b)^(2))/(1000 l_(vap))`
= `(RT_(b)^(2))/(1000 l_(vap)) = (RT_(b)M)/(1000 DELTA S_(vap))`
`("because" (Delta H_(vap))/(T_(b)) = Delta S_(vap))`
The conversion of LIQUID to gas at the boiling pointis accompanied by large increase in randomness. However, degree of randomness in vapours at their boiling point may be taken approximately constant, other factors being constant, we can use the approximation that `k_(b) PROP T_(b)`. Thus.
`K_(b) (X) = 0.68 , K_(b) (Y) = 0.53 and K_(b) (Z) = 0.98` .
