Solution: Calculate the value of Eocell  for the following reaction: 2 Co3+(aq) + 3 Ca(s) → 2 Co(s) + 3 Ca2+(aq) Co3+(aq) + 3e– →  Co(s)     Eo = 1.54 V Ca2+(aq) + 2e– →  Ca(s)     Eo = –2.87 V.    A)  –4.41 V    B)  –1.33 V    C)  –11.6 V    D)  +1.33 V    E)  +4.41 V  

Problem

Calculate the value of Eocell  for the following reaction:

2 Co3+(aq) + 3 Ca(s) → 2 Co(s) + 3 Ca2+(aq)

Co3+(aq) + 3e →  Co(s)     Eo = 1.54 V

Ca2+(aq) + 2e →  Ca(s)     Eo = –2.87 V.

 

 A)  –4.41 V    B)  –1.33 V    C)  –11.6 V    D)  +1.33 V    E)  +4.41 V
