Kinetic Theory Of Gases Question 78
Question: A non-linear triatomic gas is filled inside a vessel. If ‘a’ fraction of moles dissociate into individual atoms, then average degree of freedom for the mixture is: (neglect vibrational degrees of freedom)
Options:
A) $ \frac{3\alpha +6}{\alpha +1} $
B) $ \frac{\alpha +6}{2\alpha +1} $
C) $ \frac{3\alpha +6}{\alpha +2} $
D) $ \frac{3\alpha +6}{2\alpha +1} $
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ {f _{\max }}=\frac{( n\alpha )( 3 )( 3 )+( n-n\alpha )( 6 )}{( n\alpha )( 3 )+( n-n\alpha )}=\frac{3\alpha +6}{2\alpha +1} $
