Question

What is the relationship between the concentration of particles in a solution and the solution’s vapor pressure? As solute concentration increases, vapor pressure increases. As solute concentration increases, vapor pressure decreases. As the concentration of electrolytes increases, vapor pressure increases. However, as the concentration of nonelectrolytes increases, vapor pressure decreases. As the concentration of electrolytes increases, vapor pressure decreases. However, as the concentration of nonelectrolytes increases, vapor pressure increases.

Answer 1

Answer: B on egd

Explanation:

Answer 2

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 solvent particles at the surface decreases.

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

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