1.	An aqueous solution is `1.00` molal in `KI`. Which change will cause the vapor pressure of the solution to increase?A. Addition of waterB. Addition of NaClC. Addition of `Na_(2)SO_(4)`D. Addition of 1.00 molal KI
Answer» Correct Answer - A According to raoults low `P_(s)=PX_(A)` (`X_(A)` = mole fraction of solvent) and on addition of water the mole fraction of water in the solution increases therefore vapour pressure increases.
