Stoichiometry

Q1: Vapor pressure of a solution is proportional to(where, Sv and St are mole fraction of solvent and solute respectively).

A Sv

B 1/St

C St

D 1/Sv

ANS:A - Sv

The vapor pressure of a solution is proportional to the mole fraction of the solvent (𝑆𝑣Sv​). This relationship is described by Raoult's Law, which states that the partial pressure of a solvent above a solution is directly proportional to the mole fraction of the solvent in the solution. So, the correct option is: (a) 𝑆𝑣Sv​
