The following is a question adapted from a JC’s H2 Chemistry Test that was emailed to me by a JC student.
Let’s use the essential concepts that we have learned in the previous blogpost to solve this MCQ question.
Question:
Which gas is most likely to deviate most from ideal gas behaviour?
A. Ar
B. N2
C. CH4
D. HCl
Suggested Answer:
D
Thought Process:
Recalling what we have discussed in previous blogpost, you can will realised that HCl has stronger intermolecular forces of attraction (pd-pd in this case) between its molecules, as compared to weak van der Waals intermolecular forces between N2, Ar and CH4 molecules respectively.
Higher intermolecular forces between molecules –>Deviate most from Ideal Gas Behaviour
Hope you enjoyed yourself here. If you have anything to add, feel free to leave me a comment below.
Cheers! Stay tuned for another question related to this concept.
