Which of the following is not endothermic in nature ?
Correct answer: A. Combustion of sulphur
- A. Combustion of sulphur
- B. Gasification of carbon
- C. Thermal cracking of fuel oil
- D. Steam reforming of naphtha
Explanation
Combustion of sulphur releases heat, so it is exothermic rather than endothermic. Gasification, thermal cracking and steam reforming generally require heat input, making them endothermic processes.
