Use the Partial Activity Series Included to Determine Which Reaction $\rightarrow$

Use the partial activity series included to determine which reaction will NOT occur spontaneously. Zn $\rightarrow$ Zn²⁺ + 2e^-
Fe $\rightarrow$ Fe²⁺ + 2e^-
Co $\rightarrow$ Co²⁺ + 2e^-
Ni $\rightarrow$ Ni²⁺ + 2e^-
Cu $\rightarrow$ Cu²⁺ + 2e^-

A) Fe (s) + Co²⁺ (aq) $\rightarrow$ Fe²⁺ (aq) + Co (s)
B) Zn (s) + Ni²⁺ (aq) $\rightarrow$ Zn²⁺ (aq) + Ni (s)
C) Co (s) + Fe²⁺ (aq) $\rightarrow$ Co²⁺ (aq) + Fe (s)
D) Ni (s) + Cu²⁺ (aq) $\rightarrow$ Ni²⁺ (aq) + Cu (s)
