Question
A new type of galvanic fuel cell is being developed which uses the following half- reactions: - I included a picture that shows the half-reactions to use for the questions. A) What is the standard cell potential for this cell?  B) What is the overall reaction for this cell?  C) How much work can this cell do under standard conditions? D) If a cell is charged with 1 atm H2, 1 atm N2, 0.400 M N2H4, 0.00100 M OH- in 5.0 L of water, then what is the cell potential for this cell? Will it be spontaneous under these conditions?  E) What would be the effect on the cell potential if the pH of this system were decreased?
