Collision Theory Experiment

Collision Theory Experiment temperature increases the number of collisions. As the temperature rises, all the particles move fast. If they move faster, they will have more clashes. [IMAGE] Concentration (or pressure) increases the number of collisions. Higher solution concentrations mean that there are more reactant particles between the water molecules, which makes them more prone to significant inter-particle collisions.

The collision theory states that 'a chemical reaction occurs when reactant particles collide with sufficient energy', so collision theory occurs in my experiment (John Holman p. 225). By raising the temperature, I give a large amount of energy to reactant particles, causing more collisions and causing more reactions. As the temperature rises the reaction rate increases, but when the temperature exceeds 50 ° C., the reaction rate begins to decline as the enzyme begins to denature. This is a chart explaining what happened in my experiment.

Collision theory explains how chemical reactions occur and reaction rates are different. In order to react, the particles must collide. If a collision causes a chemical change, it is called a "fruitful" collision. And that is a theory that explains how chemical reactions occur and why reaction rates change. In order to react, reactant particles must collide. Only a small percentage of total collisions will cause chemical changes, which are called productive collisions. Productive collisions have sufficient energy (activation energy) to break existing bonds and form new bonds at impact, thereby producing reaction products. Increasing the concentration of the reactants and increasing the temperature will cause more collisions, which will result in more productive collisions, which will increase the reaction rate.

Collision theory is used in particular to predict the rate of chemical reactions to gases. Collision theory is based on the assumption that reactive species (atoms or molecules) must come together or collide for the reaction to take place. However, not all conflicts bring about chemical changes. Collisions can effectively produce chemical changes only when the species are brought together and some minimal internal energy is equal to the activation energy of the reaction. In addition, the collision species must be oriented to facilitate the necessary rearrangement of atoms and electrons. Therefore, according to collision theory, the rate at which a chemical reaction progresses is equal to the frequency of effective collisions.
