Gases like `CO_(2)` and `CH_(4)` show more deviation from the ideal gas behaviour as compared to gases like `H_(2)` and `He`, Explain

Text Solution

Verified by Experts

In `CO_(2)` and `CH_(4)`. The molecular size is more as compared to `H_(2)` and `He`. Therefore, if we neglect the molecular bvolume in these gases in the same as we do for `H_(2)` and `He`. The deviations from the ideal gas beheviour are likely to be more.

Out of CO_(2) and NH_(3) gases, which is expectd to show more deviation from the ideal gas behaviour ?

Gases deviate from ideal behaviour because mole-cules:

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressyre and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas beheviour as compared to the gases which are liqufied with diffculty.
