What is the relationship between the concentration of particles in a solution and the solution’s vapor pressure? As solute conce
kap26 [50]

Answer:

As solute concentration increases, vapor pressure decreases.  

Step-by-step explanation:

As solute concentration increases, the number of solute particles at the surface of the solution increases, so the number of <em>solvent </em>particles at the surface <em>decreases</em>.

Since there are fewer solvent particles available to evaporate from the surface, the vapour pressure decreases.

C. and D. are <em>wrong</em>. The vapour pressure depends <em>only</em> on the number of particles. It does not depend on the nature of the particles.
