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 have a great impact on chemistry. It benefits on comprehension of chemical reaction processes (Kinetics of the Iodine Clock Reaction).

The amount of iodine in seawater is 0.06% mg/l, and the total amount of iodine in the sea is 93 billion tons, which is much more than the land reserves. The amount of iodine in seawater is mostly in the form of organic compounds of iodine such as amines and synthesis. There are many seaweed plants that can absorb iodine, such as the kelp, which is known as iodide and has a high concentration of iodine. The amount of iodine in dried seaweed is 0.3-0.5 percent, some as high as 1 percent, and about 100,000 times more than the concentration of iodine in seawater. The iodine content of kelp is very high, and the concentration of iodine in the cell is much higher than that in the extracellular environment. Therefore, example of the terrine formation inside and outside the cell cannot be explained by simple passive transport. The ability of cells to maintain constant ion cascade is due to the active transport of the cell with an inverse concentration gradient. Therefore, the transport process of the material adverse concentration gradient is called active transport. This process requires total energy. Active transport characteristics are followings: First, specificity kelp iodine intake quickly, but calcium transport speed is very slow, this is because it contains a certain transport carrier. Next, speed can reach saturation state kelp unlimited high iodine content, because transport carrier of iodine is limited, cannot continue to absorb iodine …show more content…
