Show hintHide hint
Think about the relationship between the solid and liquid phases.
Question 2.
What does equilibrium mean in environmental terms?
Show hintHide hint
Consider what happens when a system stabilizes.
3Question 3.
What does K_oc represent?
- A liquid phase concentration
- A partition coefficient
- A moisture content measure
Show hintHide hint
Consider what this coefficient refers to.
4Question 4.
True or False: At equilibrium, the concentrations of all phases remain constant.
- True
- False
Show hintHide hint
Refer back to the definition of equilibrium.
Question 5.
Given a closed system with 1,000 kg of water and 2,000 kg of soil, how would you set up a mass balance equation for 200 kg of a contaminant added?
Show hintHide hint
Sketching the balance can help visualize the distribution.
Question 6.
Discuss the effects of a higher K_oc value versus lower K_oc value on remediation strategies.
Show hintHide hint
Consider how easy it is to extract versus how tightly it's held.
