A copper penny dropped into a solution of nitric acid produces a mixture of nitrogen oxides.The following reaction describes the formation of NO, one of the products.
3Cu(s)+8H+(aq)+2NO−3(aq)2NO(g)+3Cu2+(aq)+4H2O(l)
E°cell for this reaction is 0.620 V.
What is the value of E°rxn at 300 K when [H+] = 0.100 M, [NO3–] = 0.0350 M, [Cu2+] = 0.0200 M, and the partial pressure of NO is 0.00300 atm? V
