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 |
