Question
Be sure to answer all parts. Consider the following reaction: Cd(s) + Fe2*(aq) - Cd2*(aq) + Fe(s) E° (Fe2+ / Fe) = -0.4400 V, E° (Cd²+ / Cd) = -0.4000 V Calculate the emf for this reaction at 298 K if [Fe²*] = 0.75 M and [Cd²*] = 0.010 M. E = V Will the reaction occur spontaneously at these conditions? yes no cannot predict
