Cracking is___________________?
Correct answer: A. An endothermic reaction
- A. An endothermic reaction
- B. An exothermic reaction
- C. Favoured at very low temperature
- D. None of these
Explanation
Cracking breaks large hydrocarbon molecules into smaller ones and requires heat to rupture their bonds, so it is endothermic. Consequently, cracking units need continuous heat input rather than operation at very low temperature.
