Air/fuel ratio by weight for combustion of methane with theoretical quantity of air will be about ____________________?
Correct answer: B. 17 : 1
- A. 9 : 1
- B. 17 : 1
- C. 23 : 1
- D. 29 : 1
Explanation
For CH₄, the stoichiometric reaction requires two moles of O₂; with air containing about 23.2% oxygen by mass, the required air is approximately 275 g per 16 g methane. Thus the air-to-fuel ratio is about 17:1.
