The pressure exerted by `1 mol` of `CO_(2)` at `273 K` is `34.98 atm`. Assuming that volume occupied by `CO_(2)` molecules is negligible, the value of van der Waals constant for attraction of `CO_(2)` gas is

Options

A. `3.59 dm^(6) atm mol^(-2)`
B. `2.59 dm^(6) atm mol^(-2)`
C. `1.25 dm^(6) atm mol^(-2)`
D. `1.59 dm^(6) atm mol^(-2)`

Explanation

To find the value of the van der Waals constant for attraction (A) of CO₂ gas, we can use the van der Waals equation for real gases, which is given by:

\[ \left(P + \frac{a}{V^2}\right)(V - b) = RT \]

Where:
- \( P \) = pressure
- \( V \) = volume
- \( T \) = temperature
