Iodine clock reaction activation energy
WebThe rate of reaction is how fast or slow a reaction occurs relative to a standard. The greater the rate of reaction, the less time it takes for the reaction to go to completion, i.e. the less time it takes for reactants to be … WebAs soon as the Thiosulfate is used up, Iodine will begin to appear in the solution. The presence of Iodine is then dramatically detected by the formation of a blue Starch-Iodine molecular complex and the reaction is said to “Clock” at this point. (Actually, the starch molecules complex with I 3-which is formed by a reaction between I 2 and I-.)

Webautomobiles. Catalysts operate by decreasing the value of the activation energy for the reaction. The decrease in activation energy resulting from the addition of a catalyst is shown in the figure above. An effective catalyst exists for the reaction of iodide with hydrogen peroxide. The catalyst is iron (II) ions dissolved in the reaction mixture.
