One litre of `CO_(2)` is passed over hot coke. The volume becomes `1.4 L`. Find the composition of products, assuming measurement at `NTP`.

Explanation

To solve the problem of determining the composition of products when 1 liter of CO₂ is passed over hot coke, resulting in a total volume of 1.4 liters, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reaction**:
The reaction between carbon (coke) and carbon dioxide (CO₂) can be represented as:
\[
\text{CO}_2 + C \rightarrow 2 \text{CO}
