Which of the following reactions occuring during coal gasification is called the Neumann reversal reaction ?
Correct answer: C. 2CO ↔ C + CO2
- A. C + H2O ↔ CO + H2
- B. CO + H2O ↔ CO2 + H2
- C. 2CO ↔ C + CO2
- D. C + 2H2O ↔ CO2 + 2H2
Explanation
The Neumann reversal is the reverse carbon monoxide decomposition reaction, written as 2CO ⇌ C + CO2. It is closely related to carbon deposition and the Boudouard equilibrium during gasification.
