Question

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:

Step1: Understand diffusion concept

Diffusion is the movement of solute particles from an area of higher concentration to an area of lower concentration to reach equilibrium.

Step2: Calculate initial concentrations

The left - hand side has a volume of 2 mL and 3 particles, so the initial concentration is $\frac{3}{2}=1.5$ particles per mL. The right - hand side has a volume of 1 mL and 2 particles, so the initial concentration is $\frac{2}{1} = 2$ particles per mL.

Step3: Determine particle movement

Since the concentration is higher on the right - hand side, for the solute particles to reach equilibrium, more particles will move across the membrane to the left than to the right.

Answer:

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