Understanding the Terms in Combustion
Combustion is a complex chemical reaction involving fuel and oxidizer, which can lead to various outcomes. Here’s a detailed breakdown of the terms in List I matched with their respective outcomes in List II.
A. Association - 4. Exothermic
- Explanation: Association refers to the combination of smaller molecules to form larger, more complex molecules. This process typically releases energy, making it exothermic. In combustion, the formation of products from reactants releases heat and light.
B. Dissociation - 3. Endothermic
- Explanation: Dissociation is the process where larger molecules break down into smaller ones. This reaction requires energy input, thus it is endothermic. In combustion, high temperatures can lead to the dissociation of fuel molecules, absorbing energy.
C. Flame front - 1. Pseudo shock
- Explanation: The flame front represents the boundary where the combustion reaction is occurring. In certain conditions, particularly in high-speed flows, this transition can exhibit characteristics similar to a shock wave, hence termed a pseudo shock.
D. Abnormal combustion - 2. Knock
- Explanation: Abnormal combustion refers to combustion phenomena that deviate from the normal flame propagation, such as knocking in engines. This is characterized by a rapid, uncontrolled release of energy, resulting in noise and engine damage.
Conclusion
The correct matching in option (b) aligns with these explanations:
- Association (A) with Exothermic (4)
- Dissociation (B) with Endothermic (3)
- Flame front (C) with Pseudo shock (1)
- Abnormal combustion (D) with Knock (2)
Thus, the answer is indeed option (b).
