Sample Questions

Question 1
The Butler-Volmer equation describes electrode kinetics and reduces to the Tafel approximation when:
Overpotential is very small
Overpotential is sufficiently large that one exponential term dominates, giving log(i) ~ linear in η
Current is zero
Temperature is at absolute zero
Question 2
Electrochemical impedance spectroscopy (EIS) of a coated metal typically shows which behavior when the coating is intact and high-quality?
Low-frequency impedance near 10 ohm·cm2
High low-frequency impedance modulus (>10^9 ohm·cm2) and nearly pure capacitive (phase -90°) behavior
No phase shift
Only low-frequency response
Question 3
In the Pourbaix diagram for iron, cathodic protection with a target of -0.85 V CSE (~-0.55 V SHE) typically places the steel in:
The corrosion region
The region near the immunity boundary, where cathodic protection is considered adequate for most practical purposes
The transpassive region
Above the oxygen evolution line
Question 4
Which of the following best describes 'mixed potential theory' as applied to corroding metal in an aerated, slightly acidic solution?
Only hydrogen evolution matters
The metal's open-circuit potential (Ecorr) is determined by the simultaneous balance of metal dissolution (anodic) and both hydrogen evolution and oxygen reduction (cathodic) reactions
Only oxygen reduction matters
Ecorr equals the SHE
Question 5
Which of the following is TRUE about the 'Wagner-Traud' mixed-potential approach?
It applies only to one-reaction systems
It treats the metal as experiencing superposed anodic and cathodic partial reactions, each governed by its own kinetics, and Ecorr is where total anodic = total cathodic current
It requires equal Tafel slopes
It assumes diffusion-controlled conditions always
