Answer to Question #199927 in General Chemistry for Jerry

Question #199927

The standard electrode potential for the Fe2+ ↔ Fe3+ + e – half reaction is -0.770 V. a) 

Using the Nernst equation [ E = E°− ( 0.059/n) log [Oxid]/[Red]] calculate the voltage of this 

half-cell when the [Fe3+] is 1.0 x 10 -3 and [Fe2+] is 1.0 x 10 -1

. b) Calculate the approximate 

equilibrium constant (K) for the half reaction.
