Dalton's law of partial pressures supports the model of ideal gases by supporting the postulate that intermolecular forces in a gas are negligible or unimportant.
Work Step by Step
One of the postulates of the ideal gas behavior is that intermolecular forces between gas molecules are unimportant and therefore the identity and nature of the molecules are unimportant. Similarly, Dalton's law of partial pressures does not consider the nature or identity of the gas; it only takes into account the number of moles of the gas. Therefore, Dalton's law of partial pressures supports the ideal gas behavior.
