Waec Model Questions Vol1 2025 Biology Question 28
Practice objective / multiple choice question 28 from the 2025 Waec Model Questions Vol1 Biology examination.
Two diffusion experiments are carried out using the same solute. In experiment A the membrane area is 2 cm², thickness 0.01 cm and the concentration difference across the membrane is 0.5 mol L⁻¹. In experiment B the membrane area is 1 cm², thickness 0.005 cm and the concentration difference is 0.3 mol L⁻¹. Assuming diffusion rate follows Fick's law (rate ∝ A·ΔC / thickness), which experiment will have the higher diffusion rate?
