Question

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

Equilibrium in a solution means equal - concentration on both sides of a membrane. Since the left - hand side has a larger volume and more particles initially, for the solute particles to reach equilibrium (equal concentration per unit volume), more particles need to move from the left (higher concentration per unit volume initially) to the right (lower concentration per unit volume initially).

Answer:

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