Read the Assertion and Reason below and choose the correct option. — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Statement I is correct. At the Boyle temperature, $Z \approx 1$ for low to moderate pressures, and as pressure increases further, repulsive volume effects take over making $Z > 1$. Thus, overall $Z \ge 1$. Statement II is also a correct scientific fact. However, Statement II does not explain Statement I. Statement I is explained by the exact cancellation of attractive and repulsive force effects at $T_B$ at low pressures, and the dominance of repulsive 'b' at high pressures. Therefore, correct answer is B.
