Question

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

Explanation:

According to collision theory, for a reaction to occur, molecules must collide with sufficient energy (to overcome activation energy) and with proper orientation. A high - number of effective collisions require molecular collisions with energy to overcome activation energy. Low force or low kinetic energy from colliding molecules won't lead to effective collisions. Specific orientations alone are not enough without sufficient energy.

Answer:

molecular collisions with energy to overcome activation energy
