What volume of dioxygen is required for complete combustion of 2 volume of acetylene gas at NTP ?

Options

A. 2 volumes
B. 5 volumes
C. 10 volumes
D. 4 volumes

Explanation

To solve the problem of determining the volume of dioxygen required for the complete combustion of 2 volumes of acetylene gas at NTP (Normal Temperature and Pressure), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chemical Reaction**:
The combustion of acetylene (C₂H₂) can be represented by the following balanced chemical equation:
\[
\text{C}_2\text{H}_2 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O}
