Kinetic theory

activation energy (explain later on keep reading). One of which is to increase the temperature of the reaction. As temperature increases the rate of reaction increases. This is because the particles becomes more energetic causing them to have more kinetic energy as a result they move faster and more collisions occur with the required Ea (collision frequency increases). Using this knowledge, to speed up a reaction, there needs to be an increase in the number of energetic particles (those with…

relatively well. In this lab, we teste the theory of the conservation of energy. The kinetic energy at the bottom of the ramp should equal the potential energy at the top of the ramp without regard to the path taken. Thus, for method 1, the equations for kinetic energy (1/2mv²) and potential gravitational energy (U_g=mgh) were used. For the second method, the concepts and formulas for constant acceleration was used in conjunction with the equation for kinetic energy. The equation, d_y=v_i t+1/2…

Causing the increase of particles that then have enough kinetic energy to react when they collide. This Landolt Iodine Clock reaction: Oxidation of Bisulphite by Iodate is to be investigated. The aim of the experiment will be to discover whether a change in heat and concentration will increase the rate of reaction…

temperature of the chemicals, this is because that if the temperature of the chemicals increase, the reactant particles will eventually move quicker, and that there will be more energy, which particles will then collide more often, and that the average kinetic energy of the particles will increase as well, leading to an increase of the rate of reaction. Therefore it is very important to let this variable to stay constant in the experiment. Concentration is one crucial part to the experiment.…

understand how an egg drops, the knowledge of the history of physics, the engineering behind a device, and the mathematics and physics of free-fall is needed. Physics originates in its classical form in Ancient Greece. Thales was the first physicist. The theories Thales made gave the discipline of physics its name. Thales believes that the world, although made of many materials, was really made of only one element: water. The interaction of water between the phases of solid, liquid, and gas…

Introduction: Every company wants to improve the quality of their product which in turn will increase the market potential of their product. Food companies are also among those companies those have always tried to develop new ways to provide fresh and healthy foods to their customers. In this process, they have to face some difficulties. These difficulties usually happen in the sorting phase of foods. Everyone knows after the passage of time, every food item loses its freshness. As a result, it…

Background Research Chemical kinetics is the research of chemical processes which relates to the mechanisms and rates of chemical reactions (Sciencebuddies). The mechanisms describe variations of each molecule during the chemical action such as which bond is broken, which bond together newly, and how the three-dimensional shape of the chemical changes (Sciencebuddies). The rate of the reaction is measuring the speed of the chemical reactions (Sciencebuddies). Study of chemical kinetics would…

rate of a reaction will increase by a factor of two for every 10°C jump in temperature. Increased temperature is directly related to an increase in molecular motion, which means that there will be more effective collisions. According to the collision theory, the more effective collisions that occur, and the faster a reaction occurs. This is because an effective…
