Determination of a Rate Law and Temperature Dependence of a Rate Constant By Marvin Coleman March 7‚ 2011 Abstract: From the shown calculations & graphical analysis‚ the experimentally determined rate law is rate = K[I-].969 [H2O2].991 and the experimentally determined activation energy is 59.50 kJ/mole. Introduction: The rate of a reaction varies at different temperatures and reactant concentrations. In this experiment‚ the orders and dependence of the rate constant of the products

Discussion Heart Rate Our hypothesis stated 1.) The heart rate increases substantially when a person performs a physical activity and 2.) Females have heart rates greater than males’. In this experiment we measured the resting heart rates and exercise heart rates of both the male and females that are in the class. We calculated the results that were taken by each member of each group in the class (6 males and 16 females total). The average resting heart rate for women was 71.8 beats per minute

My beginning thought was I would find whole numbers but that would be to easy. My answers were all with decimals. I found that my rate law Is k (HCl)1.36 (Na2S2O3)0.84. I was expecting the solution to change color but I never thought it would turn

Determination of the Rate Constant for a Chemical Reaction Department of Chemistry Abstract This experiment was performed to determine the rate constant k‚ for hydrolysis of tertiary butyl chloride to tertiary butanol. The solvent system for this reaction is 45% isopropyl alcohol and 55% water. The rate of hydrolysis of t-butyl chloride is measured by the decrease in the concentration of this reagent with time. The rate of decomposition of t-butyl chloride must be equal to the rate of formation
Premium Chemical reaction Chemistry Reaction rate
The rate of a chemical reaction is the measure of change in concentration of the reactants of the change in concentration of the products per time. The rate of a chemical reaction is influenced by the concentration of the reactants‚ temperature‚ and the presence or absence of a catalyst. Through finding the time and concentrations of the reactants‚ it is possible to find the rate of reaction and k. To perform this experiment‚ you need two erlenmeyer flasks‚a timer‚ a LabQuest with a temperature
