In fact, the collision theory says that not every collision is successful, even if molecules are moving with enough energy. A. FALSE A vehicle strikes a parked vehicle The frequency of collisions between \(A\) and \(B\) in a gas is proportional to the concentration of each; if [A] is doubled, the frequency of \(A-B\) collisions will double, and doubling \([B]\) will have the same effect. If all collisions lead to products, then the rate of a bimolecular process is first-order in A and in B, or second-order overall: The need for collisions fundamental to any analysis of an ordinary reaction mechanism and explains why termolecular processes (three species colliding and reaction) are so uncommon.
