13 lut 2023 · Collision theory explains why different reactions occur at different rates, and suggests ways to change the rate of a reaction. Collision theory states that for a chemical reaction to occur, the reacting particles must collide with one another.

We will begin our analysis by considering two-particle collision. We introduce the concept of the relative velocity between two particles and show that it is independent of the choice of reference frame.
We are going to use this law to study collisions. Elastic means that an object deformed by an external force rapidly returns to its original shape when the force is removed. Work done deforming the object is reversible. Plastic (or inelastic) means that an object deformed by an external force is permanently deformed even after the force is removed.
In Chapter 3, we presented a number of rate laws that depended on both concentration and temperature. For the elementary reaction. We want to provide at least a qualitative understanding of why the rate law takes this form. We will first develop the collision rate, using collision theory for hard spheres of cross section Sr, 2 AB .
The collision theory states that when the right reactant particles strike each other, only a definite fraction of the collisions induce any significant or noticeable chemical change; these successful changes are called successful collisions and are possible only if reacting molecules have sufficient energy at the moment
Before and after collision, all velocities are along the x direction and one of the two bodies is at rest before the collision. The mass mA is moving towards right while mass mB at rest (vB1 = 0) . The index 1: before collision, 2: after collision. Find the velocity of each object.
