The van der Waals constant '' introduces a pressure correction to the ideal gas law. Which of the fo — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Statements A, B, and C are true. The pressure correction is $P_{correction} = an^2/V^2$, yielding units of $\text{atm L}^2\text{ mol}^{-2}$. High '$a$' means strong attraction, leading to higher critical temperatures and easier liquefaction. Statement D is false; '$a$' is a characteristic constant strictly dependent on the specific chemical nature of the gas.
