Use the Table of Electrode Potentials to Determine Which of the Following

Use the table of electrode potentials to determine which of the following reactions isn't spontaneous under standard conditions.

A) Zn(s) + 2 H⁺(aq) $\rightarrow$ Zn²⁺(aq) + H₂(g)
B) 2 Ag(s) + Zn²⁺(aq) $\rightarrow$ 2 Ag⁺(aq) + Zn(s)
C) Cl₂(aq) + 2 Fe²⁺(aq) $\rightarrow$ 2 Cl^-(aq) + 2 Fe³⁺(aq)
D) 2 Al(s) + 3/2 O₂(g) + 6 H⁺(aq) $\rightarrow$ 2 Al³⁺(aq) + 3 H₂O(l)
E) Mg(s) + Cl₂(g) $\rightarrow$ MgCl₂(s)
