Average molar kinetic energy of (CO) and (N\_2) at same temp... | Chemistry | SolveeIt

Question

Average molar kinetic energy of $CO$ and $N_2$ at same temperature is:

$KE_1=KE_2$

$KE_1>KE_2$

$KE_1<KE_2$

$\text {Can't say\ anything.\ Both volumes\ are\ not \ given}$ .

Answer

$KE_1=KE_2$

Explanation

Solution

The average molar kinetic energy of gas molecules is given by the kinetic theory of gases and is proportional to their absolute temperature (in Kelvin). It does not depend on the specific gas. So, for $CO$ and $N_2$ at the same temperature, their average molar kinetic energies would be the same:

Therefore, the correct option is (A): $KE_1=KE_2$
