Electrochemistry And Oxidation Reduction Reactions

Question 1

The half-reaction with the more positive E°_red will be ______

Answer 1

Reduced
It is the stronger oxidizing agent

Question 2

The half-reaction with the less positive E°_red will be _________

Answer 2

Oxidized
It is the stronger reducing agent

Question 3

The ________ of a wave is _________ proportional to __________, and thus ___________ proportional to __________

Answer 3

The energy of a wave is directly proportional to frequency, and thus inversely proportional to wavelength

E = hf = hc/λ

Question 4

Energy of waves in increasing order:

Answer 4

(Highest energy & shortest wavelength) Radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays (lowest energy & highest wavelength)

(HE SW) Roman, Men, Invented, Very, Unusual, X-ray, Guns (LE HW)

Question 5

Equation for electroplating:

Answer 5

(l)(t) / (n)(F) = moles of product

l = current (in amps)
t = time (in seconds)
n = moles of electrons transferred per mole of product
F = Faraday’s constant (96,500 C/mol e^-)

Question 6

substances that have a more positive electrode potential can oxidize those that have a _______ positive electrode potential

Answer 6

less
