Question:
Which of the following is an example of an exothermic reaction?
Which of the following is an example of an exothermic reaction?
Show Hint
Exothermic reactions release heat, so look for reactions where energy is a product.
Updated On: Jun 16, 2025
- Photosynthesis
- Combustion of methane
- Melting of ice
- Evaporation of water
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
An exothermic reaction is one that releases energy in the form of heat. The combustion of methane is a classic example of an exothermic reaction, where methane reacts with oxygen to produce carbon dioxide and water, releasing energy: \[ \text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O} + \text{Energy} \]
Therefore, the correct answer is: \[ \boxed{(B) \, \text{Combustion of methane}} \]
Therefore, the correct answer is: \[ \boxed{(B) \, \text{Combustion of methane}} \]
