![**Methane and Oxygen Reaction to Form Formaldehyde**
Methane and oxygen react in the presence of a catalyst to form formaldehyde according to the following reaction:
\[ \text{CH}_4 + \text{O}_2 \rightarrow \text{HCHO} + \text{H}_2\text{O} \]
A parallel reaction also occurs, where methane is oxidized to carbon dioxide and water:
\[ \text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O} \]
The feed to the reactor contains equimolar amounts of methane and oxygen.
The fractional conversion of methane is 0.90, and the fractional yield of formaldehyde is 0.855.
**Questions:**
1. What is the mol percent of formaldehyde in the reactor output?
- [Text Box for Answer]
2. What is the selectivity of formaldehyde synthesis relative to carbon dioxide synthesis?
