Effective collision -- a collision between two reactants with the correct orientation and with sufficient energy to overcome the activation energy barrier (6.9) Show all terms that begin with the letter:
1 Most collisions tend to be partially to completely elastic. 2  Momentum is conserved in an elastic collision but not in an inelastic collision. 3  The kinetic energy of an object remains constant during an elastic collision. 4  Elastic collisions occur when the collision force is a non-contact force.
