Choose the two half-reactions from a table of standard reduction potentials that most closely approximate the reaction that occur within the battery (Pacemaker). What is the standard voltage generated by a cell operating with these half-reactions? (i got +3.85V). The actual Voltage is about +3.5V)
2Li(s)+ Ag2CrO4(s)---> Li2CrO4(s)+2Ag(s)
Calculate the voltage at body temperature, 37°C. (How do i determine Q with no concentration or pressure values given)?
