Course Reader page46 example of "Gold and Nitric Acid"

Postby Joyce 3H » Sat Feb 07, 2015 4:31 pm

Why NO3(2-) can be reduced to NO rather than NO2 or N2 in the half reaction? I believe it is somehow related to stability of the product but I am not sure how to explain it thoroughly.
Thank you in advance!

I don't think you have to stress over this because we will usually be given the equations such that we are either given the half-reactions or the overall equation (you will have the find the half-reactions from the overall equation). I think in the course reader, Professor Lavelle just happened to have these half-reactions as an example because that is how the creation proceeds. Also, you can always look at the chart for possible half-reactions to use!
