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

Some people base the middle class by its wealth‚ income‚ consumption‚ and aspiration. Tuition rates have increased over the past year and even the wealthiest family haven’t been able to keep up with the cost of college tuition.

and Effects on High Divorce Rates Since the past‚ people have gotten married and lived together. Some married couples are unable to maintain their relationship as a couple; therefore‚ they choose to get a divorce. Furthermore‚ half of American marriages now end in divorce. There are three main causes to this increase in divorces: the changes in women’s roles‚ stress in modern living‚ and lack of communication. The first significant cause in the rise in the divorce rate is that women have changed

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

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

The Effect of pH on Enzymatic Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of

Assignment #2: Global Crime Rate Comparative Criminal Justice-CRJ330 Sharita L. Riddick Strayer University Professor Susan Wind April 28‚ 2013 When it comes to any type of crime it is just not a good picture to paint. All across the nation crime is a worldwide problem that directly indirectly touches every one of us in multiple ways: as victims‚ in paying higher prices for products and services‚ and in living with the consequences of fear and corruption. The primary reason to understand
