Question

someone give answer for my questions please....​

Answer 1

Answer:

3.75

Explanation:

Degrees of freedom for non linear triatomic gas excluding vibration is 6 and that for monoatomic is 3.

Let there are $N$ molecules.

50% dissociate, leaving $N/2$ triatomic molecules and $3\times N/2$ monoatomic molecules.

Thus, the degrees of freedom of mixture is:

$\frac{6\times \frac{N}{2}+ 3\times \frac{3N}{2}}{(N/2)+ (3N/2)}\\</p><p>=\frac{15}{4}\\</p><p>=3.75$
