Question

Give the two assumptions of kinetic molecular theory of gases that do not hold good in explaining the deviation of real gases from Ideal behaviour.

Answer 1

well, kinetic theory of gases laterally based on assumption. but two most important assumptions of this theory that do not hold good in explaining the deviation of real gases from ideal behaviour are ...

1. the volume occupied by each gaseous molecule is negligibly small as compared to total volume of the gas. this assumption is valid only at high temperature and low pressure but at high pressure and low temperature , volume of gas can't consider as negligible compare to total volume of the gas.
2. similarly, second assumption is, attractive force between gaseous molecules is negligible. but this assumption is not valid when pressure is high and temperature is low. at high pressure and low temperature, volume of gas small is comparable and then force of attraction between them can't be ignored.

Answer 2

VOLUME CORRECTION AND PRESSURE CORRECTION
