3.1 Galvanic Cells
LO 3.12 I can make qualitative or quantitative predictions about galvanic or electrolytic reactions based on half-cell reactions and potentials and/or Faraday's laws.

3.1b Voltaic Cells
3.2 Electrolysis
LO 3.13 I can analyze data regarding galvanic or electrolytic cells to identify properties of the underlying redox reactions.
LO 5.15 I can explain how the application of external energy sources or the coupling of favorable with unfavorable reactions can be used to cause processes that are not thermodynamically favorable to become favorable.

3.2a Electrolysis of water (Again)
Explore Objectives
- Identify the half reaction occurring at the anode and the cathode, respectively. How do you know?
- What's the structural difference between an electrolytic cell and a voltaic/galvanic cell?
- What is a nonspontaneous redox reaction? How is this different from a galvanic cell?
- Using Faraday's law, calculate the amount of gas produced at each electrode given that your energy source is a 9-Volt battery, producing a current of 2.1 amps, and you ran the reaction for approximately 2 minutes.
3.2b NonSpontaneous Reactions
Bozeman Science survey of non-spontaneous reactions in biological system.
