Question

At Boyle temperature:

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

Answer 1

Answer: (A)

the effects of the repulsive and attractive intermolecular forces just offset each other

The Boyle temperature is the temperature at which a non ideal gas behaves most like an ideal gas.

At this temperature that the attractive forces and the repulsive forces acting on the gas particles balance out.

Therefore vapor pressure = atmospheric pressure
