1.A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. The properties of the products are different from those of the reactants. ... If a physical change occurs, the physical properties of a substance will change, but its chemical identity will remain the same.
2.In order for a chemical reaction to take place, the reactants must collide. The collision between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. ... Energy is required to break a bond between atoms.
3.Effective collisions are those that result in a chemical reaction. In order to produce an effective collision, reactant particles must possess some minimum amount of energy. ... If reactant particles do not possess the required activation energy when they collide, they bounce off each other without reacting.
