An investigation on the activation energy for the iodine clock reaction Introduction: The iodine clock reaction is a presentation of chemical kinetics‚ which are the elements that affect the rate of chemical reactions. When the two colorless solutions are incorporated together‚ no reaction can be spotted. But after a short period of time‚ the solution turns into a dark blue solution. The term rate of reaction is stated as the decrease in the concentration of one of the reactions or the increase

RELATIONSHIPS THAT CONCENTRATION AND TEMPERATURE HAVE ON THE RATE OF REACTION Aim To study the effect that temperature and concentration of iodide ion solution have on the rate of iodide ion I⁻ oxidation by peroxodisulphate ion S₂O₈⁻‚ creating an iodine clock reaction. Introduction I decided to choose as the topic for my investigation the rate of reaction for its vital importance in the human body. Indeed I am really interested in Biology and especially physiology and I would like to study medicine. The

sprinkle the quarters on the morning town‚” which is to say‚ he heard the bell toll each quarter of an hour as though it were raining down upon him just to mock him. The man counted them one-by-one until‚ on the final ring before he met his fate‚ “the clock collected in the tower its strength‚ and struck”. The clock’s strength refers most probably to how heavily it must ring. To the man‚ on that final quarter hour toll‚ it must have sounded as heavily as he had ever heard it. For‚ truly‚ it would be the

Death Clock: Stimulus B. In Greenview the Howth clock stood over the town like a guardian. ‘TICK TOCK TICK TOCK’ it went as it counted the hours‚ minutes and seconds of every day. On the outskirts was the Greenview forest which contained all the memories of our childhood‚ building forts and playing hide and go seek. On the other side of town led to the crusty salty ocean coast which cooled our hot sweaty bodies after a fun afternoon out exploring the forest. This was what life like was before…

Clock reactions If you choose a project that explores the kinetics of a chemical reaction you will need a way of measuring the rate of the reaction. Clock reactions provide an interesting way of doing this for some systems. In a typical reaction the first part of a graph showing the concentration of product against time is

century medical scientists made a surprising discovery: that we are built not just of flesh and blood but also of time. They were able to demonstrate that we all have an internal "body clock" which regulates the rise and fall of our body energies‚ making us different from one day to the next. The idea of an internal "body clock" should not be surprising‚ since the lives of most living things are dominated by the 24-hour night-and-day cycle. The most obvious feature of this cycle is the way we feel tired
