ABSTRACT
-------------------------------------------------
-------------------------------------------------
In everyday life, several reactions are encountered, but still knowledge on how fast these occur and the factors affecting it were still insufficient. This study aimed to determine the different factors affecting the rate of reaction and how these factors affected it. An experiment named iodine clock reaction was done to answer the questions raised. In this study the reaction of iodide ion and peroxodisulfate (VI) ion was analyzed with the help of thiocyanate ion. The experiment was divided into three parts. First, second, and third parts of the experiment were used to examine the effects of the reactant concentrations, temperature and the presence of catalyst to the rate of reaction, respectively. The time before the reaction proceeded was recorded and calculations were done to obtain necessary information. It was identified that increasing the reactant concentration would increase the rate of reaction. Likewise, higher temperature increased the rate. Finally, the presence of catalyst had enormous effect on the reaction rate. It increased as the catalyst was added. Based on the results obtained, it can be concluded that said factors could increase the rate of reaction by increasing the temperature or reactant concentration or by adding a catalyst on the mixture.
