The "Zebra" cell was invented in 1985 in South Africa as part of the "ZEolite Battery Research Africa" project, and is used in all-electric municipal buses and other vehicles. It uses nickel and molten sodium as its electrodes. Its overall cell reaction is
NiCl2(l) + 2Na(l) Ni(s) + 2NaCl(l)
What is the Eo for the Zebra cell?
Are the reactants in this battery at room temperature when it is operating? Explain how you know.
