Question

get 4 correct in a row
1 ml 2 ml
the volume on the left is half 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:

In diffusion, solute particles move from an area of higher concentration to an area of lower concentration to reach equilibrium. Here, the left - hand side has a higher solute concentration per unit volume initially. To reach equilibrium, more solute particles will move from the left (higher concentration per unit volume) to the right (lower concentration per unit volume).

Answer:

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