A mixture of 3 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 three times the partial pressure of carbon monoxide.
A reaction does not occur at room temperature because the collision frequency between the molecules is too low.
A reaction does not occur at room temperature because the proportion of colliding molecules with energy equal to or greater than the activation energy is negligible.
