Abstract The “Chemical Kinetics” experiment was done to investigate the changes in the rate of reaction under the effect of concentration‚ temperature‚ and presence of a catalyst. It was determined that as the concentration of reactants and the temperature increases‚ the rate of the reaction increases as well. Also‚ the reaction was run by the presence of catalyst‚ and the rate of the reaction increased drastically in the presence of it. The order of the reaction with respect to each reactant

Chemical reactions are the basis of life on earth. As human beings‚ we are little more than the naturally abundant elements of which we are composed and the reactions between the compounds that they form. After all‚ how could life exist without water? Oxygen transport in a body the size of the human body would be impossible without the aid of a complex like hemoglobin. Besides being the basis of many of life’s intangibles‚ chemistry also plays an active role in our daily lives. Take for instance

My Chemical Romance. Gerard‚ Mikey and Frank all had drug problems. Mikey and Gerard‚ on top of that had alcohol problems. They got themselves better. They knew no one else could help them. What encouraged them to get better? Themselves‚ and the music. Ray had the absolutely awful job of having to watch them go through all of this‚ on top of him trying to be the perfect guitarist. Frank would do drugs over the weekend‚ and wake up on Monday not knowing anything that had happened. Mikey felt

Rates of Chemical Reaction II Pre-Lab Summary: First we will set up the experiment as shown in Figure 2‚ and then we will fill the trough with room temperature water and record the temperature and we will also add the room temperature water to the buret until it is about 10ml from the top. If there are no leaks in the apparatus‚ we will add 10ml of KI to 15ml of distilled water in a 125ml flask. We will swirl the flask so that it achieves room temperature‚ then we will add 5ml of H2O2 and quickly
