Al is more reactive
Explanation:
3MnO₂ + 4Al → 3Mn + 2Al₂O₃.
In the above reaction, Aluminium reduces MnO2 to Mn. Aluminium is more reactive than manganese and acts as a strong reducing agent in this reaction. Al leads Mn in the ease of oxidation or Al is more strongly reducing than Mn hence Al is more reactive than manganese. As per the reactivity series, Aluminium is more reactive than manganese. The reactivity series is a series of metals, in order of reactivity from highest to lowest.
