DEVIATION FROM IDEAL BEHAVIOUR IN TERMS OF INTERMOLECULAR FORCES AND MOLECULAR SIEE, DEVIATION AT HIGH PRESSURE,
DEVIATION FROM IDEAL BEHAVIOUR IN TERMS OF INTERMOLECULAR FORCES AND MOLECULAR SIEE: As a general gas equation is used to check the non-ideal behavior of gases. The general gas equation is based upon the kinetic theory of gases. Two postulates of kinetic theory of gases are wrong. Two postulates which explain this non-ideal behavior of real gases are given below. The two wrong assumptions are; (a) There are no forces of attraction or repulsion among the gas molecules. (b) The actual volume of gas molecules is negligible as compared to the volume size non polar molecules. Among He, H 2 , NH 3 , CO 2 and N 2 gases. Ammonia, NH3 is a polar molecules which shows highest degree of deviation similar other gases show deviation according to their molecular size i-e; large size molecules show more deviation than small size molecules. The or...
