Question

Analyze each cell reaction. Identify and write the half-reaction that occurs in the anode and in the cathode. Calculate the standard cell potential and describe the reaction whether it is spontaneous or nonspontaneous.

1. Li (s) + F₂ (g) = Li⁺ (aq) + 2F^- (aq)

2. Au³⁺ (aq) + Co (s) = Au (s) + Co²⁺ (aq)

3. 2 Al (s) + 3 I₂ = 2 Al⁺³ (aq) + 6 I^-1 (aq)

4. F₂ (g) + 2Cl^-1 (aq) = 2F^-1 (aq) + Cl₂ (g)

Answer 1

1.$Li_{(s)} \to Li^{+} _{(aq)} +e^{-}$

$F_{2(g)}+2e^{-}\to 2F^{-}_{(aq)}$

The reaction is spontaneous.
