Question 1.
What is the local equilibrium assumption?
Show hintHide hint
Think about the balance in processes.
Question 2.
Define diffusion.
Show hintHide hint
It relates to how contaminants spread.
3Question 3.
What does the local equilibrium assumption imply about solute behavior?
- A) Solutes disperse evenly.
- B) Solutes don't interact with solids.
- C) Solutes equilibrate rapidly with solids.
Show hintHide hint
Consider the speed of interactions.
4Question 4.
True or False: The assumption holds in cases of rapid water flow.
- True
- False
Show hintHide hint
Think about what happens to equilibrium in fast flows.
Question 5.
Analyze a scenario with varying water flow rates and discuss the impacts on local equilibrium, developing a theoretical model for high flow conditions.
Show hintHide hint
Think outside of equilibrium's quick balance.
Question 6.
Given concentrations of 10 mg/L and 50 mg/L in sediment and water, respectively, calculate the partition coefficient K_d assuming porosity of 0.3 and density of solids as 1.5 g/cm³.
Show hintHide hint
Focus on the formula's structure for partitioning.
