Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often depends

Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly

Once Upon a Time by Gabriel OkaraOnce upon a time‚ son‚they used to laugh with their heartsand laugh with their eyes:but now they only laugh with their teeth‚while their ice-block-cold eyessearch behind my shadow.There was a time indeedthey used to shake hands with their hearts:but that’s gone‚ son.Now they shake hands without heartswhile their left hands searchmy empty pockets.‘Feel at home!’ ‘Come again’:they say‚ and when I comeagain and feelat home‚ once‚ twice‚there will be no thrice-for then

POLS 1101 2/4/13 The fact of keeping law and order when it comes to terrorism is a very important‚ but very looked over issue. Terrorism has been around since the first attack in 1920. Most of the attacks on the United States has happened in New York. The most famous and well remembered is the attack on September 11‚ 2001‚ hijackers crashed 2 commercial jets into twin towers of World Trade Center; 2 more hijacked jets were crashed into the Pentagon and a field in rural Pa. Total dead and missing

“Law and Order”: these two notions of government’s purpose have always been related. During times of trouble‚ either from foreign or domestic threats‚ a government may be forced to use law to maintain order‚ even at the expense of justice for its own citizens. The Alien and Sedition Acts of 1812 provide such an example. In a time of war‚ the U.S. government felt threatened by domestic opposition to the war and by foreign perpetrators against national security. Because the existence of the American

Catalyst on Reaction Rate Introduction: Chemical reactions can be affected by a number of different factors. Particle size‚ temperature‚ concentration of a solution‚ and catalysts play a big role in the rate of reaction‚ they determine how fast a reaction will occur. According to the collision theory‚ the rate of reaction depends on the frequency of effective collisions between particles. Every reaction is different in that they all require different conditions and factors in order to have the

which more clearly displays the relationship‚ view Figure 2. The rate at which the reaction occurred for the 100% concentration is 1.45 mg/dL per minute. For the 50%‚ the rate was 3.05 mg/dL per minute‚ and for the 25%‚ the rate was 2.76 mg/dL per minute. As seen‚ the rate fluctuated from the lowest rate at 100% and the greatest rate occurring at 50%. As mentioned earlier‚ the Collision Theory states the rate of a chemical reaction is proportional to the number of collisions that occur. One way to
