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

Exchange rate movement has been an important subject of macroeconomic analysis and market surveillance. Despite its importance‚ forecasting the exchange rate level has been a challenge for academics and market practitioners since the collapse of the Bretton Woods system. Empirical results from many of the exchange rate forecasting models in the literature have not yielded satisfactory results. This paper is constructed for the purpose of comparing the forecast performance of various competing models

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

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

Accounting rate of return The accounting rate of return (ARR) is a way of comparing the profits you expect to make from an investment to the amount you need to invest. The ARR is normally calculated as the average annual profit you expect over the life of an investment project‚ compared with the average amount of capital invested. For example‚ if a project requires an average investment of £100‚000 and is expected to produce an average annual profit of £15‚000‚ the ARR would be 15 per cent. The

It classifies cases into groups or predicts values of a dependent (target) variable based on values of independent (predictor) variables. The procedure provides validation tools for exploratory and confirmatory classification analysis. The procedure can be used for: Segmentation Identify persons who are likely to

Resting metabolic rate can vary with age independently from body mass changes in the Colorado potato beetle‚ Leptinotarsa decemlineata. Abstract A study was done by Saija Pironine‚ leena Lindstrom‚ and Anne Lyytinen in the Journal of Insect Physiology‚ to investigate the age dependence of resting metabolic rate in Colorado potato beetle (Leptinotarsadecemlineata) from adult emergence until age 10 days. In their hypothesis they expected to see a bell shaped pattern in metabolic rate with adult age
