The following question can be answered after reviewing information from Energy and Redox Reactions (and other related information).
1. Which of the two Half cell reactions indicate that electrons are being used as a reactant. ________________________
2. In all Half cells, there is energy in the reactants that is difference from the products. This energy is called ___________________.
3. The difference between the energy in the reactant and product create an energy difference that is unique to all Half cells. This energy potential difference has units of ___________________.
4. Since all these energy potentials are difference from reactant and product conditions, what chemical reaction is the basis for these value? _____________________________________.
5. Explain, in terms of energy difference, what happens as the Redox reaction proceed (making reactants into products). Does the reaction "stop", explain?
6. ________________________________ and ____________________________________ are the two major types of Electrochemistry.
7. ______________________(__________________) is the study of how a system/reaction converts electrical energy to chemical energy.
8. _______________________(_________________) is the study of how a system/reaction converts chemical energy to electrical energy.
9. Which of the above (from Q7 & Q8) would have a chemical reaction that is spontaneous, ___________________________. What is the sign of the Ecell _______________
10. Could you list any consumer products that perform both functions in Q7 and Q8 (i.e. can "flip" back and forth between Q7 & Q8 processes). _____________________________
