From among the following, choose one which is not an exothermic process ?
Correct answer: A. Catalytic cracking
- A. Catalytic cracking
- B. Methanol synthesis
- C. Ammonia synthesis
- D. Oxidation of sulphur
Explanation
Catalytic cracking requires heat to break large hydrocarbon molecules into smaller ones, so it is endothermic. Methanol synthesis, ammonia synthesis, and sulphur oxidation release heat.
