Webhi everyone :) just decided to put this here in case it helps anyone. these cells gave me a really hard time when i was first trying to learn them, but i laid out how i look at them and it's helped me sort them out in my head. let me know if you want any clarification or if any of my notes are confusing! WebBecause galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.

WebA galvanic cell is constructed in which an Ag+/Ag half cell is connected to a Ni2+/Ni half cell. Calculate delta G standard for this reaction at 25 degrees celsius: 2Ag+ (aq) + Ni (s) ---> 2Ag (s) + Ni2+ (aq) A galvanic cell has two solutions: solution one is 0.3 M FeCl2, solution two is 1.7 M MgCl2. WebThe Nernst equation is E is equal to E zero minus .0592 over n, times the log of Q. Well at equilibrium, at equilibrium E is equal to zero, so we plug that in. So we have zero is equal to the standard cell potential, E zero, minus .0592 over n, times the log of Q. But at equilibrium, remember, Q is equal to K.
