An isolated container holds 4 moles of hydrogen and 2 moles of helium at 400 K. The ratio of the total kinetic energy of the hydrogen molecules to the total kinetic energy of the helium molecules is :

Options:

Answer:

Solution:

$K = (\frac{1}{2} RT) (n) (f)$ .

$K_{H_{2}} = \frac{1}{2} RT \times 4 \times 5 = 10 RT . K_{He} = \frac{1}{2} RT \times 2 \times 3 = 3 RT .$

Ratio $= 10 : 3$ .
