Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion (A): In alumino thermite process, the metals like iron melts due to the heat evolved in the reaction.
Reason (R): The reaction is:
Fe2O3 + 2Al → Al2O3 + 2Fe
- a)Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
- b)Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
- c)Assertion (A) is true but reason (R) is false.
- d)Assertion (A) is false but reason (R) is true.
Correct answer is option 'A'. Can you explain this answer?

Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): In alumino thermite process, the metals like iron melt due to the heat evolved in the reaction.
Reason (R): The reaction is: Fe2O3 + 2Al → Al2O3 + 2Fe
To understand the given assertion and reason, let's break down the process and reaction involved.
Alumino Thermite Process:
The alumino thermite process is a type of exothermic reaction where a metal oxide is reduced by a more reactive metal. In this process, aluminum (Al) is used as the reducing agent to reduce the metal oxide, resulting in the production of molten metal.
Explanation:
- The given reaction in the alumino thermite process is Fe2O3 + 2Al → Al2O3 + 2Fe.
- In this reaction, iron(III) oxide (Fe2O3) is reduced by aluminum (Al) to produce aluminum oxide (Al2O3) and molten iron (Fe).
- The reaction is highly exothermic, meaning it releases a significant amount of heat during the reaction.
- The high temperature generated by the exothermic reaction causes the iron (Fe) to melt.
Assertion (A): In alumino thermite process, the metals like iron melt due to the heat evolved in the reaction.
Reason (R): The reaction is: Fe2O3 + 2Al → Al2O3 + 2Fe
Explanation:
- Assertion (A) is true because the high temperature generated by the exothermic reaction causes the iron to melt.
- Reason (R) is also true because it provides the chemical equation of the reaction involved in the alumino thermite process.
Conclusion:
Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
Reason (R): The reaction is: Fe2O3 + 2Al → Al2O3 + 2Fe
