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

molecular collisions that have very specific orientations

Explanation:

Based on the collision theory, a high frequency of effective collision is dependent on the molecular collisions that have very specific orientations.

The collision theory suggests that for reactions to occur, there must collision between reacting particles. The number of collision is dependent on the number of collision per unit time as well as fractions of effective collision. To attain effective collision, colliding particles must be properly oriented to give the desired product.
