According to the collision theory, which is required for a high number of effective collisions?

a very low amount of force from colliding molecules

a very low amount of kinetic energy from colliding molecules

molecular collisions that have very specific orientations

molecular collisions with energy to overcome activation energy

According to the collision theory, to have a high number of effective collision one requires A MOLECULAR COLLISIONS WITH ENERGY TO OVERCOME ACTIVATION ENERGY.

Activation energy is the energy barrier that must be overcome before a chemical reaction can take place. For a chemical reaction to occur, the particles of reactants must collide with one another effectively in order to overcome the activation energy. The products of the chemical reaction can only be formed if the activation energy is overcome.

i think the answer is composed of atoms
