APChem - electrochemistry (Ch.18)

Standard conditions, E° = ?

E° - (0.0591/n)logQ

Non standard conditions E = ?

E° - (RT/nF)lnQ

At standard temp what does K = ?

(nE°)/0.0591

What reaction happens at the anode?

Oxidation

What reaction happens at the cathode?

Reduction

The best oxidation agents …

Are easily reduced (reduction cell potential value higher)

The best reducing agents …

Have a very low cell potential value, hard to reduce

G° = ?

-nFE°

What’s the general form of line notation ?

Anode | aqueous (M), … || aqueous (M), … | cathode

How do you find the cell potential of a galvanic cell

Find both reactions in reduction table, flip one to the oxidation rxn and the sign of its cell potential. Then add both reactions.

Electrons flow from ___ to ___?

Anode to cathode

What’s an electrolytic cell

Thingamajig that uses electricity from an outside source to make a chemical reaction happen that otherwise wouldn't have happened

energy formula using frequency

E = h * freq
