Question

At Boyle temperature,

• A. The effects of the repulsive and attractive intermolecular forces just offset each other
• B. The repulsive intermolecular force are greater than the attractive intermolecular forces
• C. The repulsive intermolecular forces are lesser than the attractive intermolecular forces
• D. $b-\frac{a}{RT}>0$

Answer 1

The correct option is A The effects of the repulsive and attractive intermolecular forces just offset each other

The temperature at which the real or non-ideal gas behaves as an ideal gas over a wide range of pressue is known as Boyle temperature. Boyle temperature (TB) is related to the
Van der waal's constant a, b as given below. At this temperature, the attractive and repulsive forces acting on the gas particles arrive at a balance for a real gas.
$T_b=\frac{a}{Rb}$.
