Patterns of Irrational or Unethical Decision Making. and so the reverse reaction, the oxidation of lead by copper(II) ions, is predicted to occur spontaneously: Note that reversing the direction of a redox reaction effectively interchanges the identities of the cathode and anode half-reactions, and so the cell potential is calculated from electrode potentials in the reverse subtraction order than that for the forward reaction. Recalling the chapter on thermodynamics, the spontaneities of the forward and reverse reactions of a reversible process show a reciprocal relationship: if a process is spontaneous in one direction, it is non-spontaneous in the opposite direction. For example, I have an equation: 0.1 Zn (s) + 0.5 Ag + (aq) 0.1 ratios needed in order to calculate the balanced equation. need to divide each reactant and product with the smallest moles. The relationship between stockholders and These connections insure that the sign of the measured potential will be consistent with the sign conventions of electrochemistry per the various definitions discussed above.
