Leaching rate is independent of the________________?
Correct answer: D. None of these
- A. Agitation
- B. Temperature
- C. Particle size
- D. None of these
Explanation
Leaching rate is affected by agitation, temperature, and particle size: agitation improves contact, temperature changes diffusivity and viscosity, and smaller particles provide shorter diffusion paths. Since none of these is independent, option D is correct.
