Identify the incorrect statement from the following:

Explanation

Option B is incorrect because equal volumes of different gases at the same conditions contain the same number of molecules, not atoms. Since Argon and Krypton are monoatomic gases, the statement is misleading but generally accepted; however, the key point is the phrasing about atoms. The other statements are correct: diatomic gases have higher heat capacity than monatomic gases, 22.4 liters of any ideal gas at NTP contains Avogadro's number of molecules, and azeotropic mixtures have identical vapor and liquid compositions.
