Question

E0 and Eh respectively represent the aver age kinetic energy of a molecule of oxygen and hydrogen . If the two gases are at the same temperature , which of the following statements is true ? (A) E0 > Eh (B) E0 = Eh (C) E0 < Eh (D) Nothing can be said about the magnitude of E0 and Eh as the information given is in sufficient

Tardigrade Admin · Accepted Answer

The average kinetic energy of gas molecule,

E = \frac{3}{2} K_{B} T

where

K_{B} =

Beltzmann's constant

T =

absolute temperature
ds the question mentioned, temperature of two gas mole cules of oxygen and hydrogen is same.

∴ E_{0}

be average kinetic energy of oxygen

E_{H}

be average kinetic energy of hydragen

∴ E_{0} = E_{H}

Q. $E_{0}$ and $E_{h}$ respectively represent the aver age kinetic energy of a molecule of oxygen and hydrogen . If the two gases are at the same temperature , which of the following statements is true ?

$E_{0} > E_{h}$

$E_{0} = E_{h}$

$E_{0} < E_{h}$

Nothing can be said about the magnitude of $E_{0}$ and $E_{h}$ as the information given is in sufficient

Q. E0​ and Eh​ respectively represent the aver age kinetic energy of a molecule of oxygen and hydrogen . If the two gases are at the same temperature , which of the following statements is true ?

E0​>Eh​

E0​=Eh​

E0​<Eh​

Nothing can be said about the magnitude of E0​ and Eh​ as the information given is in sufficient
