The isotherms of 1 mole of different gases at 273 K, if the limit of pressure tending to zero, conve — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

As pressure approaches zero ($P \rightarrow 0$), all real gases converge to behave ideally. For exactly 1 mole of an ideal gas at 273 K, the product $PV$ limits to $nRT = 1 \times 0.0821 \times 273 = 22.4\text{ L-atm}$. Therefore, correct answer is B.
