Question

Under what condition will diffusion take place most rapidly? a movement through a permanent barrier b movement from an area of high concentration to an area of low concentration c movement from an area of low concentration to high concentration d movement against a concentration gradient

Answer 1

Diffusion will take place most rapidly under condition **b: movement from an area of high concentration to an area of low concentration**. This is because diffusion relies on the natural tendency of particles to move from areas where they are more concentrated to areas where they are less concentrated, seeking to reach equilibrium.
