With increase in temperature, the leaching rate increases due to__________________?
Correct answer: C. Both A. and B.
- A. Decreased liquid viscosity
- B. Increased diffusivity
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Higher temperature lowers the liquid viscosity, improving penetration and flow through the solid, while also increasing molecular diffusivity. Both effects usually increase the leaching rate.
