Question 16 : Which of the following statements is false?
The properties of N2(g) will deviate more from ideality at -100oC than at 100oC.
Molecules of an ideal gas are assumed to have no significant volume.
Molecules of CH4(g) at high pressures and low temperatures have no attractive forces between each other.
Van der Waal's equation corrects for the non-ideality of real gases.
