Temperature dependence of the electromotive force

Electromotive force, electrode reactions, electrochemical potential,
Nernst equation.
Principle
Thermodynamic data of the gross reaction in a galvanic cell can
be determined by measuring the e.m.f. at different temperatures.
Tasks
Determine the usable reaction equivalent work of the Daniell cell
by measuring the dependence of the electromotive force on
temperature.
