Question

Based on the following half- cell reactions and reduction potentials, which has the greatest tendency to be reducing agent?

a. Cd+2 + 2e- -> Cd               E° = - 0.40 V

b. Cr+2 + 3e- -> Cr                 E° = - 0.74 V

c. Fe+2 + 2e- -> Fe                E° = - 0.44 V

d. Zn+2 + 2e- -> Zn                 E° = - 0.76 V

Cd" + 2 + Cd E = - 0.40 V Cr + 3 + Cr - 0.74 V Fe + 2 -→ Fe E = -0.44 V Zn + 2* - Zn E = - 0.76 V
Transcribed Image Text:Cd" + 2 + Cd E = - 0.40 V Cr + 3 + Cr - 0.74 V Fe + 2 -→ Fe E = -0.44 V Zn + 2* - Zn E = - 0.76 V
