19 An effective collision between reactant particles requires the particles to have the proper

(1) charge and mass

(2) charge and orientation

(3) energy and mass

(4) energy and orientation

(4) energy and orientation

They need the energy to be able to break the original bonds, and they need the orientation to be able to bond with the new atoms

The answer is energy and orientation. While the two. chemicals reacts, the molecules on each reactions has to come together with enough energy and force for the chemical reaction to take place. This is among the theory of Collison.
