Answer |
| Cell diagram shorthand |
Anode/anode solution//cathode solution/cathode |
| reduction occurs where... |
cathode |
| If the cell voltage (E°) is postive... |
the reaction is spontaneous |
| if the cell voltage (E°) is negative... |
the reaction is non-spontaneous |
| in a galvanic cell the anode is _________; and the cathode is___________ |
negative, positive |
| the more negative the reduction potential... |
the stronger the product is as a reducing agent. |
| the more positve the reducing potential... |
the stronger the reactant is as an oxidiazing agent |
| Gibbs Free energy for a redox reaction |
= - nFE; n = number of moles of electrons transfered; F = Faraday constand (96500); E = cell voltage given |
| Galavonic/Voltaic cells... |
transfer of electrons uses spontaneous redox reaction to generate an electric current |
| Electrolytic cells... |
uses external voltage source to create an electric current that forces a non-spontaneous redox reaction to occur. |
| electrons move from... |
the anode to the cathode |
| oxidation occurs where... |
anode |
| in an electrolytic cell the anode is ________; and the cathode is ________ |
positive, negative |
| a Faraday is equal to... |
96500 C |
