Answer to Question #279926 in General Chemistry for lester

Question

Which of the following statement is not true regarding kinetic molecular theory?

Answer 1

Real gases approach ideal behavior at high temperature and low pressure.

At a low temperature and high pressure, the molecules come near to each other. So, the molecular interaction terms become significant. In the derivation of the ideal gas equation, it was assumed that there is no molecular interaction. But, at low temperature, this does not occur. So, deviation from ideality occurs.
