Question

at a constant temperature, which of the gases will have the highest average kinetic energy? answer: a h₂ b n₂ c o₂ d f₂ e all the gases will have the same average kinetic energy.

Explanation:

According to the kinetic - molecular theory of gases, the average kinetic energy of gas molecules is given by the formula \(E_{k}=\frac{3}{2}kT\), where \(k\) is the Boltzmann constant and \(T\) is the absolute temperature. At a constant temperature \(T\), the value of \(E_{k}\) depends only on \(T\) and not on the type of gas (i.e., not on the molar mass or any other property of the specific gas molecule).

Answer:

E. All the gases will have the same average kinetic energy.
