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

💡 Solution & Explanation

Statement I is generally considered correct within the strict theoretical framework of the basic van der Waals model (they are treated as empirical constants for a specific gas). Statement II is also correct as a definitional statement. However, Statement II is simply defining a theoretical "van der Waals gas" and does not logically explain *why* the parameters 'a' and 'b' are independent of temperature. Therefore, correct answer is B.
