Table 2 Half-Reaction Standard Reduction Potential, E (V) [Zn(OH),]- + 2 e Zn + 4 OH -1.20 Zn(OH), + 2e- → Zn + 2 OH -1.25 HgO + H2O + 2 e Hg + 20H +0.10 O2 + 2 H20 + 4e +4OH +0.40 Pacemakers are electronic devices that help regulate the heart rate. Currently, lithium-iodine cells are commonly used to power pacemakers and have replaced zinc-mercury cells. Table 1 provides the operating cell potential, E, for each cell. Table 2 provides the standard reduction potentials for several half-reactions related to zinc-mercury and zinc-air cells. The use of zinc-mercury cells in hearing aids has been replaced by zinc-air cells that operate using the oxidation of Zn by O, from the air, generating a potential of +1.60 V. Table 2 provides the standard reduction potentials for the half-reactions used in zinc-mercury and zinc-air cells. Which of the following best explains the modification to the cell design that is mostly responsible for the difference in standard cell potentials for zinc-mercury and zinc-air cells? The greater standard cell potential of the Zn-air cell compared to that of the zinc-mercury cell most likely results from the thermodynamically more favorable reduction of O, compared to A HgO. The greater standard cell potential of the Zn-air cell compared to that of the zinc-mercury cell most likely results from the greater number of moles of e required to reduce O, compared to в HgO. The greater standard cell potential of the Zn-air cell compared to that of the zinc-mercury cell most likely results from the thermodynamically less favorable reduction of O, compared to HgO. The greater standard cell potential of the Zn-air cell compared to that of the zinc-mercury cell most likely results from the greater number of moles of hydroxide ions required to reduce D [Zn(OH),- compared to Zn(OH),.
