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

reaction used to determine the experimental rate law of is 2I-(aq) + H2O2(aq) I2(aq) + 2H2O2(l). The rate law determined experimentally is rate= k[I-]1.017[H2O2]0.927. Additionally by performing essentially the same experiments but with temperature changes one can determine how k is affected by temperature changes and the new activation energy. Also‚ from graphs the activation energy was determined to be 33.3 kJ/mol. INTRODUCTION: The rate of a chemical reaction often depends on reactant

and willing to work yet is unable to find a job. Unemployment rate is the number of people officially unemployed divided by the labor force. Official unemployment measures those over the age of 16 who are able for employment‚ but are unable to obtain a job. The labor force is the number of people over the age of 16 who are either employed or unemployed. In year 2005‚ unemployment rate in Malaysia (3.0%) higher than unemployment rate in Cambodia (2.5%).

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
