Document Summary
25 mc: 10 electrochemistry, 10 kinetics and 5 from thermodynamics (each mc worth 2 marks) 2 pages of written answers related to electrochemistry and kinetics only (29 marks total on these 2 pages) Oxidation: loss of electrons by an atom, molecule, ion, etc. Reduction: gain of electrons by an atom, molecule, ion, etc. Oxidation-reduction or redox reaction involves both the gain (reduction) and loss (oxidation) of electrons. Oxidizing agent: causes another species to be oxidized by accepting/taking electrons from it (this species undergoes reduction) Reducing agent: causes another species to be reduced by donating electrons to it (this species undergoes oxidation) Galvanic/voltaic cell: a cell in which a spontaneous chemical process is used to produce electrical energy (e. g. chemical energy is transformed into electrical energy) Electrolytic cell: a cell in which electrical energy is used to bring about a non-spontaneous process (e. g. electrical energy is transformed into chemical energy)
