WebJan 12, 2024 · I have some doubts regarding the Van der Waals' equation which relates the Pressure, volume and temperature of real gases. It is given by : ( P r e a l + a n 2 V 2) ( V − n b) = n R T I also read that P i d e a l = P r e a l + a n 2 V 2 I know that the term ( V − n b) represents the volume remaining for a real gas. WebThe Van der Waals Equation derivation is explained below. Derivation of Van der Waals equation. For a real gas, using the Van der Waals equation, the volume of a real gas is given as (Vm – b), where b is the volume occupied per mole. Therefore, ideal gas law when substituted with V = V m – b is given as:
WebThe van der Waals equation improves upon the ideal gas law by adding two terms: one to account for the volume of the gas molecules (correcting V V, shown in red below) and another for the attractive forces between them (correcting P P, shown in blue below). P V =nRT (P + an2 V 2)(V –nb) =nRT P V = n R T ( P + a n 2 V 2) ( V – n b) = n R T. WebDec 7, 2024 · London dispersion forces are defined as the intermolecular forces that occur between atoms and between non polar molecules as a result of the motion of electrons while van der Waals forces are the weakest intermolecular force and consist of dipole-dipole forces and dispersion forces. They are interchangeable and are both the weakest forces. …
