Statement I: Graham's law is a limiting law, i.e., it is best applied at low pressures for gases. St — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Graham's Law assumes ideal gas behavior, which holds best at low pressures where intermolecular forces are negligible (Statement I is correct). However, Graham's Law can be applied as an approximation to real gases as well, so saying it is "valid only for ideal gases" is incorrect (Statement II is false).
