Problem The unfavourable electrochemical reaction among the following is:
a. Zn + H 2 SO 4 ⟶ ZnSO 4 + H 2 \text{Zn} + \text{H}_2\text{SO}_4 \longrightarrow \text{ZnSO}_4 + \text{H}_2 Zn + H 2 SO 4 ⟶ ZnSO 4 + H 2 KI + Cl 2 ⟶ KCl + I 2 \text{KI} + \text{Cl}_2 \longrightarrow \text{KCl} + \text{I}_2 KI + Cl 2 ⟶ KCl + I 2 KCl + I 2 ⟶ KI + ICl \text{KCl} + \text{I}_2 \longrightarrow \text{KI} + \text{ICl} KCl + I 2 ⟶ KI + ICl Al + 3 HCl ⟶ AlCl 3 + 3 2 H 2 \text{Al} + 3\text{HCl} \longrightarrow \text{AlCl}_3 + \frac{3}{2}\text{H}_2 Al + 3 HCl ⟶ AlCl 3 + 2 3 H 2 Browse the problem library
