Which statement is correct?
There is no reaction to form carbon dioxide and water because the molecules do not collide with sufficient energy.
There is no reaction to form carbon dioxide and water because the molecules do not collide with sufficient frequency.
The mean velocity of the methane molecules is less than that of the oxygen molecules.
The partial pressure of each gas is the same.
