Electrochemistry

QuestionAnswer
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
