RESULTS 28⁰C was the optimal temperature. 28⁰C had the maximum rate of reaction for the class data and results provided by this experiment; the results were represented graphically in graph 1 and graph 2. The reason for having 2 tables and graphs is because 28⁰C was done twice. Data for 28⁰C was collected in this experiment and it was collected again by peers in the classroom. Results are identical because all temperatures except 28⁰C was collected once from peers. Based on the results from the

with various sucrose concentrations and were placed into beakers of different sucrose solutions. Overall the results showed that the higher percentage of concentration gradient of sucrose‚ the more the artificial cells absorbed. Introduction: The phenomenon being investigated in the lab was how the concentration gradient affects the rate of osmosis in a cell. Osmosis is the passive movement of water from and area of high concentration‚ temperature‚ and pressure. The concentration gradient is the difference

Effect of Catalase at Different Temperatures Abstract The role of this experiment is to determine the effect of temperature on enzymatic activity. The results of the experiment were the colder the temperature the slower the reaction rate and the hotter the temperature the faster the reaction rate. Introduction Enzymes are chemical substances found in living cells and they act as catalysts of the various chemical reactions that occur in them.(Preszler‚ 2012) They bind to substrates that have

Abstract: The 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

The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

internal temperature so that the body processes can take place efficiently. The process ensures an equilibrium system is attained for all the body processes. The body temperature of an average individual is 37˚ C. this temperature fluctuates depending on activities one does. A human being is in constant movement unless they are asleep. As such‚ the temperature may increase or decrease thereby varying from this average. Some of the factors that may lead to increase in the body temperature include digestion
