The given potential is the potential for the full reaction: 11ea8937_ab9d_9860_a16d_e5ade1dc032c_TB4499_11 + 2H₂ ⟶ 11ea8937_ab9d_985f_a16d_a163c52ec02a_TB4499_00 To find the potential of the half-reaction, we need to divide the given potential by 2 (since the balanced equation shows that the half-reaction involves only one mole of electrons): EF1F1F1S1F1F1F10 = 0.92 V / 2 = 0.46 V Therefore, the best choice is C.
