When steam is passed over coal resulting in the endothermic reaction represent by, C + H2O = CO + H2, it is called the _______________ of coal?
Correct answer: B. Gasification
- A. Carbonisation
- B. Gasification
- C. Coalification
- D. Oxidation
Explanation
Passing steam over coal to form CO and H₂ is gasification, because solid carbon is converted into a combustible gaseous mixture. Carbonisation instead produces coke by heating coal in the absence of air.
