The Standard Potential for the Reaction Zn + 2Ag⁺ →

The standard potential for the reaction Zn + 2Ag⁺ → Zn²⁺ + 2Ag is 1.56 V. Given that the standard reduction potential for Ag⁺ + e^- → Ag is 0.80 V, determine the standard reduction potential for Zn²⁺ + 2e^- → Zn.

A) 0.04 V
B) -0.38 V
C) -0.76 V
D) 0.76 V
E) none of these
