With increase in temperature, the leaching rate increases because of the _____________________?
Correct answer: C. Both A. and B.
- A. Increased diffusivity
- B. Decreased viscosity of liquid
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Higher temperature generally increases molecular diffusivity and lowers liquid viscosity, reducing resistance to solute movement during leaching. Both effects therefore increase the leaching rate.
