Average molar kinetic energy of O2 and N2 at same temperature is

Question

Average molar kinetic energy of O2 and N2 at same temperature is (A) KE1 = KE2 (B) KE1 > KE2 (C) KE1 < KE2 (D) can't say anything about it. Both volumes are not given

Tardigrade Admin · Accepted Answer

K.E. = (3/2)RT (for one mole of a gas) As temperatures are same and KE is independent of molecular mass, so KE1 = KE2

Q. Average molar kinetic energy of $O_{2}$ and $N_{2}$ at same temperature is

$K E_{1} = K E_{2}$

$K E_{1} > K E_{2}$

$K E_{1} < K E_{2}$

can't say anything about it. Both volumes are not given

$K . E . = \frac{3}{2} RT$ (for one mole of a gas) As temperatures are same and KE is independent of molecular mass, so $K E_{1} = K E_{2}$

Q. Average molar kinetic energy of O2​ and N2​ at same temperature is

KE1​=KE2​

KE1​>KE2​

KE1​<KE2​
