Problem

What is the standard electrode potential for a voltaic cell constructed in the appropriate way from these two half-cells? 

Standard Reduction Potentials                   E°     

Cr 3+ (aq) + 3e → Cr(s)                        – 0.74 V

Co 2+ (aq) + 2e– → Co(s)                     – 0.28 V

 

A) – 1.02 V

B) 0.46 V

C) 0.64 V

D) 1.02 V
