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 major difference is that the operating potential of the lithium-iodine cell indicates its' cell reaction is more thermodynamically favorable.
<h3>What is the difference in cell potential?</h3>
The Zinc-Mercury Cell reaction is; Zn + HgO = ZnO + Hg. It also has long storage life and stable voltage(1.35V).
The major difference between the zinc-mercury cell and the lithium-iodine cell is that during the initial cell operation, each reaction is thermodynamically favorable, but the larger operating potential of the lithium-iodine cell indicates that its cell reaction is more thermodynamically favorable.
Matter becomes energy. Law of thermodynamics states that matter can't be created or destroyed, but can transfer to another form. If it was closed in with the form of energy, it would be transferred to the form of energy.
