Dear student,
 
Adding solute to a given solvent in a closed container decreases the rate of evaporation.
When we add a solute to the solvent, some of the solute molecules will take the surface of the liquid. As only solvent molecules located at the surface can evaporate, the sheer presence of the solute lowers the number of solvent molecules and therefore lowers the equilibrium vapor pressure.
