- 10 L
- 11.2 L
- 5.6 L
- 2.24 L

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Decarboxylation reaction:
\[
CH_3COONa + NaOH \rightarrow CH_4 + Na_2CO_3.
\]
Step 2: Molar mass sodium acetate = 82 g/mol. \[ \text{mole}=\frac{8.2}{82}=0.1. \]
Step 3: 1 mole salt → 1 mole CH$_4$.
Step 4: Volume at NTP: \[ V=0.1\times22.4=2.24\text{ L}. \] Hence → (D).
Step 2: Molar mass sodium acetate = 82 g/mol. \[ \text{mole}=\frac{8.2}{82}=0.1. \]
Step 3: 1 mole salt → 1 mole CH$_4$.
Step 4: Volume at NTP: \[ V=0.1\times22.4=2.24\text{ L}. \] Hence → (D).
