OAT - Chem

Chapter 11 - Redox Rxns and Electrochem

TermDefinition
Electrochemistry study of relationship btwn chem rxns and electrical E
Electrochemical rxns include spontaneous rxns that produce electrical E and nonspontaneous rxns that use electrical E to produce chemical change
redox rxn coupled oxidation and reduction rxns occuring simultaneously
oxidizing agent gets reduced and causes another atom to be oxidized; NAD+
reducing agent gets oxidized and causes another atom to be reduced; NADH
Oxidation Numbers assigned to atoms to keep track of redistribution of e- during chemical rxn
Electrochemical cells contained systems where redox rxns occur
Galvanic Cell where spontaneous rxns occur; G is negative, energy used to do work
Electrolytic Cell where nonspontaneous rxns occur; positive G
Anode where oxidation occurs
Cathode where reduction occurs
charge of e- 1.6E-19 C
Faraday's Constant 96,487 C/mol e-
reduction potential tendency of a species to acquire e- and be reduced
standard electromotive force (emf) difference in potential btwn two half-cells
If emf is positive then G is negative, ln K is positive, products are favored, and rxn is spontaneous

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
