In the case of real gases, the equation of state, PV = RT (where P, V and T are respectively the pressure, volume and absolute temperature), is strictly satisfied only if corrections are applied to the measured pressure P and the measured volume V. The corrections for P and V arise respectively due to
- a)kinetic energy of molecules and collision of molecules
- b)size of molecules and expansion of the container
- c)expansion of the container and intermolecular attraction
- d)intermolecular attraction and the size of molecules
Correct answer is 'D'. Can you explain this answer?

According to kinetic theory of gases there is no intermolecular force of attraction between the molecule of gases but its not true as gases liquifise, at high pressure molecular interaction starts due to which pressure on the walls decreases as molecule dragged back so pressure exerted by real gas is less than ideal gas, due to repulsive forces molecule behave as small spheres and hence volume decreases

**Explanation:**
The equation of state for real gases, PV = RT, is an ideal gas equation that assumes that the gas molecules have no volume and do not interact with each other. However, in reality, gas molecules do occupy space and experience intermolecular attractions. Therefore, corrections need to be applied to account for these deviations from ideal behavior.
**Corrections for Pressure (P):**
The measured pressure of a real gas needs to be corrected to account for the size of the gas molecules. The pressure measured by a pressure gauge is the sum of both the pressure exerted by the gas molecules hitting the walls of the container and the pressure exerted by the gas molecules colliding with the gauge. This collision pressure is due to the size of the gas molecules.
**Corrections for Volume (V):**
The measured volume of a real gas needs to be corrected to account for the intermolecular attractions between the gas molecules. The volume measured by a measuring device is the sum of both the actual volume occupied by the gas molecules and the additional space that is occupied due to intermolecular attractions. This additional space is due to the size of the gas molecules and the attractive forces between them.
**Explanation of Option D:**
Option D states that the corrections for P and V arise due to intermolecular attraction and the size of molecules. This is the correct answer because it correctly identifies the two main factors that need to be considered for the corrections.
- Intermolecular attraction: The correction for the measured volume accounts for the additional space occupied by the gas molecules due to intermolecular attractions. These attractions cause the gas molecules to be closer together, taking up more space than would be predicted by the ideal gas equation.
- Size of molecules: The correction for the measured pressure accounts for the collision pressure exerted by the gas molecules due to their size. The gas molecules have a finite volume and collide with the walls of the container and any measuring device, contributing to the measured pressure.
Therefore, option D correctly identifies both the intermolecular attraction and the size of molecules as the factors that require corrections to the measured pressure and volume in order to satisfy the equation of state for real gases, PV = RT.
