EEE 350 Questions and Correct Answers/
Latest Update / Already Graded
environmental sustainability
Ans: everything that we need for our survival/well-being
depends directly or indirectly on our natural environment
alkalinity
Ans: measure of a water's capacity to neutralize acids
adsorption
Ans: chemical adsorbs to the surface
absorption
Ans: chemical absorbs (partitions) into a phase (3D)
organic compounds (OC)
Ans: many are hydrophobic, energetically unfavorable
compounds to be dissolved in water
sorption

Ans: influences mobility, natural degradation, and engineered
remediation of pollutants
sorbate
Ans: substance being captured, sticking to or soaking into
sorbent
sorbent
Ans: solid material that does the capturing
1/n < 1
Ans: surface becomes saturated
1/n > 1
Ans: sorbate modifies original surface + enhances sorption
octanol

carbon on soil

partitioning
Ans: determines the fate of compound after it enters
environment
batch reactor
Ans: no mass flows into or out of the reactor
change in concentration results from chemical reaction only
ex: sealed beaker
d[C]/dt= -k[C]^n
completely mixed flow (CMFR)
Ans: concentration at any location within reactor volume is
constant
C_out = C_in / (1+kv/Q)
Ct/Co = e^-(Q/v + k )t
plug flow reactor (PFR)
Ans: not mixing between plugs as they move through the
reactor
net chemical reaction within the plug
V(dC/dt) = -VkC
