Aluminium being more reactive displaces the manganese metal and forms a new compound. Hence it is a displacement reaction.
The heat is also released along with the formation of products, hence it is an exothermic reaction.

This is an example of displacement and exothermic reaction because in this the highly reactive metal displaces the less reactive metal from its salt and heat is produced this so it is exothermic reaction.

Understanding the Reaction
The reaction given is:
3MnO2(s) + 4Al(s) → 3Mn(l) + 2Al2O5(s) + Heat
This is a significant combustion reaction where manganese dioxide reacts with aluminum.
Type of Reaction
- Displacement Reaction: This reaction is classified as a displacement reaction because aluminum displaces manganese from manganese dioxide. In this process, aluminum reduces MnO2, leading to the formation of liquid manganese (Mn).
- Reduction and Oxidation: Aluminum acts as a reducing agent, while manganese dioxide is reduced. The overall electron transfer signifies a displacement mechanism.
Exothermic Nature of the Reaction
- Release of Heat: The reaction releases heat, indicating it is exothermic. In exothermic reactions, energy is released to the surroundings, which can often be observed as an increase in temperature.
- Thermodynamic Favorability: The formation of stable products (liquid manganese and aluminum oxide) and the release of heat suggest that the reaction proceeds spontaneously.
Conclusion
Thus, the correct identification of the reaction as a displacement and exothermic reaction is justified. The reaction not only involves the displacement of manganese by aluminum but also releases energy in the form of heat, making option 'C' the accurate choice.
