Once we determine that the reaction is spontaneous, we have to write a cell diagram for the reaction. In part a why is H+ included in this cell? I thought it was just used to balance the equation

Hi! To my understanding, in a cell diagram we must write all the species present in each of the half reactions, unless a particular species cancels out when combining the half-reactions together. In the NO3-/NO reaction, the H+ is a species which is interacting with the gases and the electrode; therefore, we must include that in the cell diagram. I hope this helps!
