The correct answer is option (D): High temperature is favorable for adsorption. it increases with an increase in temperature
Van der Waals equation is an equation relating the relationship between the pressure, volume, temperature, and amount of real gases.

For a real gas containing ‘n’ moles, the equation is written as
Where, P, V, T, n are the pressure, volume, temperature and moles of the gas. ‘a’ and ‘b’ constants specific to each gas.
Where,
Vm: molar volume of the gas
R: universal gas constant
T: temperature
P: pressure
V: volume
Thus, Van der Waals equation can be reduced to ideal gas law as PVm = RT.
The equation can further be written as;
a: atm lit² mol-²
b: litre mol-¹
