Calculating Standard Potentials for Electrochemical Cells from Standard Electrode Potentials of the Half-Reactions

Use tabulated standard electrode potentials to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25 °C. (The equation is balanced.)

  Al (s)+ NO _3{}^{-}(a q)+4  H ^{+}(a q) \longrightarrow Al ^{3+}(a q)+ NO (g)+2  H _2 O (l)
