Energy of 10 non rigid diatomic molecules at temperature is :
Choose an option
Show full solutionCorrect option: B
Correct answer
B
Step-by-step explanation
$\begin{aligned}
& \text { Degree of freedom }(f)=5+2(3 \mathrm{~N}-5) \\
& \qquad f=5+2(3 \times 2-1)=7 \\
& \text { energy of one molecule }=\frac{f}{2} K_B T
\end{aligned}$
energy of 10 molecules
