Final answer:
In a collision between particles lacking sufficient energy or the wrong orientation, the likely outcome is that the particles would rebound, resulting in no reaction. This is called an ineffective collision.
Step-by-step explanation:
In a collision between two particles where the particles lack sufficient energy or possess the wrong orientation, the likely outcome is that the particles would rebound, resulting in no reaction. This is called an ineffective collision. The first collision illustrated in the figure in the provided information shows the particles bouncing off each other, with no rearrangement of atoms occurring.
