Calculate the exchange current density for a zinc electrode immersed in a 1.0 M solution of zinc sulfate at 25°C when the overpotential is 0.05 V. The standard reduction potential for the Zn2+/Zn couple is -0.76 V. The transfer coefficient is 0.5. Assume that the concentration of the electrolyte does not change significantly during the reaction.
