WebThis is the reaction that we need to occur for our galvanic cell. So this reaction right over here is going to be the negative of that. So it's going to be positive 0.76 volts. So one way to think about it is this wants to happen with an electromotive force or the energy per Coulomb relatively of 0.76 volts. http://ch302.cm.utexas.edu/echem/echem-cells/echem-cells.html mary seacole definition of nursing
