c) To what potential does the alloy need to be polarized

c) To what potential does the alloy need to be polarized to in order to sufficiently protect it given that the reversible potential for corrosion of this alloy is -0.45 V, the free corrosion potential (corresponding to the free corrosion rate given above) was -0.20 V, and the Butler-Volmer coefficient for anodic dissolution of the alloy, Ba, is 46 V-1 (Hint: use the information given to first calculate the exchange current density for dissolution of the alloy)
