‘Kinetics’ is the study of chemical reactions. The speed of a reaction can vary depending on many variables such as the nature of the reactants‚ particle size‚ concentration and temperature. For a chemical reaction to occur‚ there must be a collision between reactants. The reaction rate is slower when the reactants are large and complex molecules because it takes longer for the molecules to combine together creating a chemical reaction. More than 2000 years ago‚ Democritus‚ who was a philosopher

As with the earbuds and earphones‚ a radio that is too loud can prevent a driver from hearing sounds that may prevent a collision. Can I talk on my cellphone in California? As of January 2017‚ all cellphone use is banned except for hands-free use. Governor Brown signed legislation that makes it illegal to use a cellphone with your hands for any reason. The law is intended

the very beginning of earth’s history‚ this planet was a giant‚ red hot‚ roiling‚ boiling sea of molten rock - a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the collisions tapered off the earth‚ it began to cool‚ forming a thin crust on its surface. As the cooling continued‚ water vapor began to escape and condense in the earth’s early atmosphere.

for the 25%‚ the rate was 2.76 mg/dL per minute. As seen‚ the rate fluctuated from the lowest rate at 100% and the greatest rate occurring at 50%. As mentioned earlier‚ the Collision Theory states the rate of a chemical reaction is proportional to the number of collisions that occur. One way to increase the number of collisions is to increase the concentration‚ therefore proving that the data determine from this experiment is inaccurate. The expected result should have been as the

You have a window seat and all seems well. Suddenly the pilot announces over the intercom for everyone to fasten their seatbelts and prepare for landing. You look out the window and see several other aircraft flying around near the airport. Suddenly the aircraft

Chemical reactions can happen slowly or fast. The speed of the reaction rate can be changed. Some of the factors that can affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with

Enzymes INTRODUCTION Enzymes are protein cells and they are found in the gut. They help to break down the food you eat. Enzymes are produced by living cells and they speed up reactions because they are biological catalysts. If we did not have enzymes‚ the reactions in our cells would be too slow to keep us alive. This means that they are extremely important for our survival. The properties of enzymes are: ⋆ They can be used many times‚ because they can speed up reactions without

that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to the Collision Theory‚ during a reaction‚ particles collide with each other and react if the geometry of the collision is correct. In this Experiment‚ we will investigate the effect of varying concentrations of Potassium Iodide on its reaction with Hydrogen peroxide‚ which will stay at a fixed concentration. This
