The vapour pressure of a dilute solution of a solute is not influenced by
1 Temperature of solution
2 Melting point of solute
3 Mole fraction of solute
4 Degree of dissociation of solute
Explanation:
V.P. is independent of melting point of solute.

The molar heat of vaporization of toluene is \({\rm{\Delta }}{{\rm{H}}_{\rm{v}}}\). If its vapor pressure at 315 K is 60 torr and that at 355 K is 300 torr, then the value of \({\rm{\Delta }}{{\rm{H}}_{\rm{v}}}\) ? \(\left( {{\rm{log2 = 0}}{\rm{.3}}} \right)\)

Which combination of following terms is matched correctly? (I) Vapour pressure (II) Intermolecular forces (III) Latent heat of vaporisation
1 High - I, Weak - II, Small - III
2 High - I, Strong - II, Large - III
3 Low - I, Weak - II, Large - III
4 Low - I, Strong - II, Small - III
Explanation:
\({\text{Liquid}} \rightleftharpoons {\text{Vapour}}\) (1) If vapour pressure is high, it means equilibrium is in forward side. This is attained when intermolecular forces holding the molecules are of weak nature. Low heat is required to convert liquid into vapour. Thus, (1) is correct. (2) Thus, incorrect. (3) When vapour pressure is low, it means inter molecular forces are strong hence (3) is incorrect. (4) When, vapour pressure is low, intermolecular forces are strong, hence large heat is required thus, option (4) is incorrect.
