Statement I: At constant volume, the pressure of a fixed amount of an ideal gas is ∝ its absolute te — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Statement I is Gay-Lussac's Law (P ∝ T at constant V). Statement II is also correct because molecular speed (and thus collision frequency and momentum transfer) is ∝ √T. Since P is ∝ the product of collision frequency (∝ √T) and impact force (∝ √T), we get P ∝ T. But Statement II is not the standard direct explanation.
