Consider a simple bimolecular step: If the two molecules \(A\) and \(B\) are to react, they must approach closely enough to disrupt some of their existing bonds and to permit the creation of any new ones that are needed in the products. 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.
