Question

If number of molecules of h2 are double than that of o2 then the ratio of kinetic energy of hydrogen and that of oxygen at 300k is

Answer 1

Hii dear,

# Answer - 1:1

# Explaination-
- The average kinetic energy translation per molecule of all gases is same for all gases at same temperature and is given by,
K.E. = 3/2 kT

- Hence for hydrogen molecules
K.E.(H2) = 3/2 kT
K.E.(O2) = 1.5×1.380×300 = 621J

- Also for oxygen molecules
K.E.(O2) = 3/2 kT
K.E.(O2) = 1.5×1.380×300 = 621J

K.E.(H2)/K.E.(O2) = 621/621 = 1
- Therefore, Ratio of hydrogen to oxygen is 1.

Hope that helped you...
