Question

get 4 correct in a row
3 ml 1 ml
the volume on the left is three times as large as the volume on the right. which of the following statements describes how the solution will change over time?
for the solute particles to reach equilibrium, more particles will move across the membrane to the left than to the right.
for the solute particles to reach equilibrium, more particles will move across the membrane to the right than to the left.
because the solute particles have reached equilibrium, the same number of particles will move across the membrane in each direction.

Explanation:

Step1: Calculate solute - particle concentrations

The left - hand side has 6 particles in 3 mL, so the concentration is $\frac{6}{3}=2$ particles/mL. The right - hand side has 1 particle in 1 mL, so the concentration is 1 particle/mL.

Step2: Understand diffusion principle

Solute particles move from an area of higher concentration to an area of lower concentration to reach equilibrium. Here, the higher - concentration area is on the left and the lower - concentration area is on the right. So, more particles will move from the left to the right to equalize the concentrations.

Answer:

For the solute particles to reach equilibrium, more particles will move across the membrane to the right than to the left.
