Question
![### Problem Statement
A batch combustion chamber is loaded with 151 moles of methane and 909 moles of air (21.0 mol% O₂). The methane combusts to form only carbon dioxide and water, but some methane may remain unburned. At interruption, the reactor contains 59.69 moles of O₂.
#### Questions:
a) Enter the correct stoichiometric coefficients.
\[ \text{CH}_4 + \_\_ \text{O}_2 \rightarrow \_\_ \text{CO}_2 + \_\_ \text{H}_2\text{O} \]
b) Which reactant is limiting?
c) What is the extent of reaction at interruption?
d) How many moles of each species are present at interruption?
### Explanation:
For question (a), the task is to balance the combustion reaction of methane. The general reaction is:
\[ \text{CH}_4 + 2 \text{O}_2 \rightarrow \text{CO}_2 + 2 \text{H}_2\text{O} \]
For question (b), determine the limiting reactant by comparing the initial moles of CH₄ and available O₂ from air in the stoichiometry balanced equation.
For question (c), calculate the extent of the reaction given the remaining moles of O₂ are 59.69 mol. Use the stoichiometry of the balanced equation and initial moles to find the extent.
For question (d), calculate the remaining moles of each species (CH₄, O₂, CO₂, H₂O) using the extent of reaction and stoichiometric calculations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F43e319bd-a9e3-47ea-9380-e4fa6843211a%2F47946123-fe15-4487-8ae3-4f6ef2d686c0%2Fsi9hjek_processed.jpeg&w=3840&q=75)
