Problem
In a gas-phase elementary reaction between molecules A and B, most collisions do not form products even when the colliding species possess energies equal to or greater than the activation energy. Which of the following must also be satisfied for a collision to be successful?
(a) A catalyst must be present to lower the activation energy further.
(b) The collision must be perfectly head-on to ensure maximum energy transfer.
(c) The reactant molecules must approach with an orientation that allows the necessary bonds to break and form.
(d) The activated complex must have a potential energy lower than that of the reactants.
