A mixture of 2 dm3 of carbon monoxide and 1 dm3 of oxygen is stored in a sealed container at room temperature (298 K).
Which statement is correct?
The mean velocity of the oxygen molecules is greater than that of the carbon monoxide molecules.
The partial pressure of oxygen is twice that of carbon monoxide.
The gases do not react because the collision frequency between carbon monoxide and oxygen is too low at room temperature.
The gases do not react because the proportion of collisions with energy greater than or equal to the activation energy is negligible.
