In experiment 3, the main purpose was to determine the rate of a reaction between ethylene (dinitrilo) tetraacetate (EDTA) and chromium (III) nitrate. For that to be achieved, we reacted the two solutions and collected data. From the data we were able to get the absorbance from the transmittance using the following equations: %T=Tx100% and A=-logT. From the Absorbance we were able to get the absorbance of the Chromium using
ACr(III)= A∞ -At
In this experiment, volume and temperature are extremely important factors. The volume of each solution must be as similar to one another as they can be to ensure that the same amount of solution is reacting. Also, the temperature had to have remained constant throughout the experiment or else the results of the reaction would have been different and not reliable to compare.
As expected, The Solution of EDTA with the highest pH value (5) had the smallest percentage transmittance and the one with the smallest pH value (4) had the largest percentage transmittance (see data table). This is due to the concentration of hydrogen ion is higher in a low pH solution. With all the data, we were able to graph curves representing our data and from graph we were able to calculate the …show more content…
However, if for whatever reason anything remained on the cuvette, the spectrophotometer reading might have been skewed as the light was passing through it. Anything on the cuvette including the label on the cuvette may have been a source of error when reading the percent transmittance of the different solutions. Also, the lid on the spectrophotometer must have been close properly and entirely while the spectrophotometer was taking its reading. If any excess light from the laboratory setting were able to reach into the device, it would have significantly altered the measure of percent

Nitrogen and Ethylene Yields Essay

EXTRA CREDIT Molin Cheng After reading these two articles we can see each of them use a different way to improve ethylene yield. The two have the same goal, but also has a conflict theory and each of them have its advantages and disadvantages. First, let’s talk about the article “Oxidative Pyrolysis of Ethane”, which assumes that the effects of the oxygen addition can be beneficial to industrial crack in three manners: decreased residence time or increased throughput, higher severity, or…

Essay about Nothing: Temperature and Antifreeze

inexpensive to produce and distribute, and highly soluble in water “due to its high affinity for Hydrogen bonding”. It’s boiling is lower than most coolant, which is why it is used in antifreeze, but methanol antifreeze are just a short time solution. Ethylene glycol-described when they were first introduced as a replacement for methanol in 1926 as a “permanent antifreeze.” The higher boiling point made it applicable to both hot weather and cold weather. It is also odorless, but the main downside is the…

Essay about Enzymes: Enzyme and Active Site

distortion in the tertiary structure of the enzyme molecule and change the shape of the active site therefore making no substrate molecules able to fit within the active site, therefore no enzyme substrate complexes form and therefore a slower rate of reaction. The binding of an inhibitor is either reversible or irreversible. If it is an irreversible inhibitor it will usually react with the enzyme and then change it chemically, via covalently bond formations, modifying key amino residues needed for enzymatic…

Diels-Alder Synthesis

Diels’s laboratory in 1928. Diels synthesis is a synthetic method, which is referred as the Diels-Alder reaction. The method involves the addition of diene to dienophiles. An example would be the double bonds on adjacent carbon atoms. Another example of diene synthesis is the addition of butadiene to maleic anhydride. Dienes are compounds with conjugated unsaturation. Dienes of the Diels-Alder reaction may either be cyclic or open-chain. It also hosts many substituents( an atom taking the place of another…

Ethanol: Ethanol and Large-scale Ethanol Production Essay

synthetic ethanol) is made from petrochemical feed stocks, primarily by the acid-catalyzed hydration of ethylene, represented by the chemical equation C2H4 + H2O → CH3CH2OH The catalyst is most commonly phosphoric acid, adsorbed onto a porous support such as silica gel or diatomaceous earth. This catalyst was first used for large-scale ethanol production by the Shell Oil Company in 1947. The reaction is carried out with an excess of high pressure steam at 300 °C. In the U.S., this process was used on…

Essay on Modelling in Chemical Engineering Sample

bed reactor is widely used for carrying out multiphase reaction. One example of application of fluidized bed reactor is the production of polyethylene and polypropylene [1]. The following is a simplified schematic of the bed reactor used in polymerization of polyethylene [1]. The two phases in the fluidized bed reactor are the bubble phase and the dense phase. The bubble phase contains the essential reactant for the polymerization-ethylene (or any olefin). The monomer then is transferred to the…
