EEE 350 EXAM QUESTIONS AND
ANSWERS 2026 VERIFIED.
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 - ANS surrogate for tissue or some fluids in animals or organic 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
Ct/Co = e^-kt
which reactor is more efficient? - ANS PFR is more efficient but CMFR is more common since
it can handle the spikes in flow better
