reaction rate of iodine and determine the reaction order for H+ and acetone. In order to do this, we ran 7 reactions with HCl, I2, Water, and Acetone. Every Run had different amounts of one of the components. These reactions allowed us to calculate the reaction rates for each of the 7 trials by dividing the molarity of the I2 by the time the reaction took. Next we had to determine the reaction order which required us to put each reaction rate, except for trial I, over the reaction reaction rate…

Kinetic can be defined as a study of the speeds or the rates of chemical reactions. The factors that could affect the rates of the reactions are physical state, reaction temperature, catalysts, pressure, concentration of solution, and reaction time. The change of the speed of the reaction can be predicted based on the different reaction conditions. Kinetic study is important because it can describe information about the reaction mechanism. The concentration has affected the frequency which the…

11/16/2017 Background Research Chemical kinetics is the research of chemical processes which relates to the mechanisms and rates of chemical reactions (Sciencebuddies). The mechanisms describe variations of each molecule during the chemical action such as which bond is broken, which bond together newly, and how the three-dimensional shape of the chemical changes (Sciencebuddies). The rate of the reaction is measuring the speed of the chemical reactions (Sciencebuddies). Study of chemical…

electrical impulses of the heart. Supraventricular tachycardia causes an abnormal heart rhythm, which results in the heart to beat more than 100 beats per minute. The normal resting heart rate for an adult ranges from 60 to 100 beats per minute. The term supraventricular indicates that this very fast heart rate (tachycardia) is occurring in the two upper chambers of the heart, which are referred to as the right and left atria. The right and left atria of the heart receive incoming blood and as a…

What effects do different conditions have on the rate of reaction? Clarissa Reyna University of Texas Rio Grande Valley October 31, 2017 T.A: Marcia Calderon ABSTRACT: The motive behind this two week lab experiment was to analyze what different conditions have on the rate of reaction. These different conditions included changing amounts of concentration in the substrates and enzymes, having the enzymes set up in different temperature environments and adding different amounts of the…

The cardiac cycle is the sequence of events that occurs when the heart beats. It take 0.8 seconds for a normal cardiac cycle for atrial and ventricle. It take atrial systole 0.1 sec, atrial diastole 0.7 sec, ventricular systole 0.3 sec, and ventricular diastole 0.5 seconds. In this biological pump, heart muscle tissue contracts in the upper chamber - called the atria - and proceed to ventricles. After that it relaxes there are two basics phases of the cardiac cycle: diastole and systole. When…

Chemical kinetics focuses on the rates in which chemical reactions take place; in other words, it describes how quickly reactants are consumed and how quickly products are produced. When observing the reaction rate, an important factor to take into consideration is the reactant concentration, in which the rate is ultimately dependent on. To determine the rate order, data must be collected experimentally and then analyzed using Excel. Because the initial concentrations of each trial are known in…

form iodide. In order to determine the kinetic properties of this reaction, 2S2O3(aq) + I2 (aq) S4O62-(aq) +2I-(aq), the derived rate expression was used to discover the order of reactants and rate constant. After running multiple trials for four runs with differing concentrations of IO3-, I-, H+, the times were recorded. Using those average times, the initial rate of each run was measured as 5.72x10-6M/s for Run 1, 3.68x10-5M/s for Run 2, 1.21x10-5M/s for Run 3, and 0.000269M/s for Run 4.…

Claim: The more heavily concentrated the reactant is that is losing an electron is, the faster the reaction rate. Evidence & Analysis: To appropriately support how more heavily concentrated reactants result in a faster reaction rate, a colorimeter was used. The colorimeter detected changes in color, or the absorbance of a chemical reaction. In this lab, the reactants were KI and FeCl3; when these chemicals reacted, they produced a color change that was detected by the colorimeter. Five…

Experiment B3: Chemical Kinetics Lab Report Determination of Order of the reaction and Rate Constant Based on the equation 1, the reaction rate was observed under different concentration of I- and S2O82- where k is the rate constant while x and y are the reaction orders I- and S2O82- respectively. Rate = k[I-]x[S2O82-]y Equation 1 The value of x from Equation 1 was determined from various concentrations of the I- while the…
