Factors that affect the rate of reaction The rate of reaction speed refers to the quantity of the precursor or reduced the quantity of a product that increases the time unit of measure of the substance may be obtained from the volume or mass concentrations of substances changed after the reaction, which can write the formula as follows: The reduced quantity of precursor Chemical reaction rate =--------------------------------------- The reaction time. The increase in the quantity of chemical products. = ---------------------------------------- The reaction time. The chemical reactions that occur all around us that some reactions occur very quickly, but some of the reactions, it happens slowly, and even the chemical reaction caused by the same type of precursor. Sometimes it also happens with different rate of speed by the speed of the reaction depends on the type of precursor and various environmental factors. Is as follows: 1. the type of precursor Precursor to each have a different chemical reaction. One passenger, the initial reaction may be, it can be faster with a slow reaction may occur, but with another type. For example, magnesium metal can react with acid, a solution gas, hydrogen, oxygen, magnesium, but will react with the metal is very slow or. Sodium can react with the water very quickly. While magnesium metal to react with water, slowly, etc. 2. the concentration of precursor reactions, most will come more quickly. If we use the precursor is more intense due to the increasing concentration of the substance is made of a combination of haimianu sector is massively more. Particles of the substance so there is a chance collision and reaction. 3. the temperature or the heat will affect the internal energy substance by adding temperature increases the kinetic energy of the particle, irrespective of the substance causes the particles of the substance move faster. Increase opportunities for collision of the particles, the more. In addition to increasing power, irrespective of the substance will help make the substance is greater than the energy within the power establishment, kamman, a faster reaction, such as storing food in the refrigerator to prevent spoilage, etc. 4. the catalytic is filled into the reactions of these buses will have no effect on the occurrence of the products of the reaction causes the reaction, but it would have the effect to reduce the power of the reaction, but kamman construction will be effective to reduce the power of the reaction makes the work that kamman reactions occur more easily, and after the reaction. Catalytic entered into the property and the amount still intact. By catalysis that can be found in everyday life, including various enzymes in our body that Catalysis occurs, as it helps digestion very quickly. 5. the delayed reaction is a chemical reaction that is filled in by these substances will have no effect on the occurrence of the product of the reaction, but it would have to increase its power, construction, chemical reactions, kamman reaction has been more difficult or inhibit the reaction. A chemical reaction, and there is a delay as the original mass. But there may be some visual properties such as changes in size or shape changed by the reaction delay found in everyday life: preservatives in foods that inhibits reactions that cause spoilage of food, etc. 6. the surface area of a precursor In the case of a solid precursor To increase the surface area of the substance will help speed up chemical reaction occurs due to the increased surface area allows for a space made of chemical reactions, and more. For example, bird food, chew proof-luen, will help make smaller and has more surface area, the water in the digestive tract can be accessed easier digestion, etc. 7. pressure is the substance that is the gas can react well because of increasing pressure to make your visit to the gas molecules closer together. There are a number of gas molecules per unit area increased, so have the opportunity to bump into each other and a greater reaction that this was similar to the case of a substance that has a lot of concentration to be reaction more quickly enough.
