Question

Which of the following expressions correctly represents the
relationship between the average molar kinetic energy, KE,
of CO and N2 molecules at the same temperature ?
(a) KE꜀ₒ < KEN2
(b) KE꜀ₒ > KEN2
(c) KE꜀ₒ = KEN2
(d) cannot be predicted unless volumes of the gases are
given

Answer 1

Answer:

The answer is may be the a

Answer 2

The correct representation of the relationship between the average molar kinetic energy, of $\bold{CO\,and\,NO_{2}}$ is $\widetilde{KE}_{CO}=\widetilde{KE}_{N_{2}}$

Step by step explanation:

The average kinetic energy is calculated by the following formula.

                           $\bold{Kinetic\, energy=\frac{3}{2}RT}$

• It is independent of the nature of gas
• It is dependent on the temperature of the gas.

At same temperature, the kinetic energy of two gases are equal to each other.

Therefore, the correct expression for the given condition is $\widetilde{KE}_{CO}=\widetilde{KE}_{N_{2}}$.

Hence, correct option is "c".
