Question
Heart pacemakers are often powered by lithium–silver
chromate “button” batteries. The overall cell reaction is
2 Li(s) + Ag2CrO4(s)---->Li2CrO4(s) + 2 Ag(s)
(a) Lithium metal is the reactant at one of the electrodes
of the battery. Is it the anode or the cathode? (b) What
standard emf would be generated by a voltaic cell based on
these half-reactions? (c) The battery generates an emf of
+3.5 V. How close is this value to the one calculated in part
(b)? (d) Calculate the emf that would be generated at body
temperature, 37 °C. How does this compare to the emf you
calculated in part (b)?
