Question

$CO_{2}(O - C - O)$ is a triatomic gas. Mean kinetic energy of one gram gas will be (If N-Avogadro's number, k-Boltzmann's constant and molecular weight of $CO_{2} = 44$ )

Answer 1

Solution

Mean kinetic energy for μ mole gas $= \mu.\frac{f}{2}RT$

∴ $E = \mu\frac{7}{2}RT = \left( \frac{m}{M} \right)\frac{7}{2}NkT = \frac{1}{44}\left( \frac{7}{2} \right)NkT$

$= \frac{7}{88}NkT$ [As f = 7 and M = 44 for $CO_{2}$ ]
