Environmental chemists plot the negative log of this quantity against pH on the phase diagrams of active metals like iron and uranium. Proteins in the inner mitochondrial membrane are arranged so this quantity increases from Complex I (“one”) to Complex III (0[2])(“three”) to Complex IV (“four”) to oxygen. (0[2])Reactivity series rank elements by this (0[1])quantity (0[1])relative to a value of zero for hydrogen (20[1])on platinum (20[2]0[2])in (20[1])a (0[2])(*) SHE (10[1])(“she”) cell. (10[1])This quantity for a reaction is proportional to negative delta-G and decreases (0[1])by “RT (0[1])over nF times the natural (10[1])log (10[1])of Q” (10[1]0[1])if it is not run at standard state. This quantity (0[1])is subtracted between two half-reactions to determine the emf (“E-M-F”) and direction of a (0[1])redox reaction. For 10 points, name this quantity computed using the Nernst equation (10[2]0[1])and measured in volts. (10[2]0[6])■END■ (10[8]0[8])
