Chemiluminescence Lab Report

The temperature can have a major impact on an enzyme. According to Campbell Biology author Reece etc. 2011 “The enzyme reaction will increase as the temperature increase with the increasing temperature….substrates collide with active sites more frequently when the molecules move rapidly.”(Reece etc 2011) Every enzyme hits its optimal temperature the reaction will be at its highest point.(Reece etc. 2011) When the

Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC, which is the body temperature, where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working.

As the temperature increases, so will the rate of enzyme reaction. However, as the temperature exceeds the optimum the rate of reaction will decrease.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

Three factors that can affect the rate of reaction are temperature, pH and the salinity.

Abstract: This two part experiment is designed to determine the rate law of the following reaction, 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L), and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1, and the experimental activation energy is 60.62 KJ/mol.

If different temperatures are used to catalyze enzyme activity, then the lowest temperature would produce the quickest reaction rate because enzymes can become denaturized at higher temperatures

Question: How does changing enzyme concentration or temperature affect the reaction time of enzyme activity?

This image explains that the higher the temperature, the concentration, and the pressure the faster the rate of the reaction is.

Hypothesis: If the temperature increases, then rate of the chemical reaction will increase as well, and if the temperature decreases, then the rate of reaction will also decrease.

(5 pts) List and explain the names and affiliations of the various characters/stakeholders in this story – I’m looking for us to use the story to map out the complexities that are generally associated with solving public health puzzles – the stakeholders you list and explain here should apply to many of the cases we consider going forward.

Chemiluminescence is a reaction well known to those who enjoy crime scene shows. Luminol is first synthesized in the experiment. Then, the crude luminol produced is oxidized to release photons giving off a light blue glow in a dark room. In a crime scene show, the blood acts as a catalyst aiding in the oxidation of luminol and hydrogen peroxide resulting in the blue glow 1.

If the acid is made more concentrated there are more particles, which means collisions are more likely. So, the higher the concentration, the quicker the reaction time is. Temperature also affects the rate of reaction. If the temperature is increased, the particles move quicker so more collisions happen. This means the higher the temperature, the

Chemiluminescence is the production of light from a chemical reaction.In this chemical reaction, two chemicals react to produce an excited intermediate which breaks down releasing it’s energy as photon’s of light to reach it’s ground state. This reaction can be seen in a glow stick when a solid ester reacts with hydrogen peroxide producing phenol and cyclic peroxide. Cyclic peroxide then reacts with the dye in the glow stick to ultimately create the glow. The glow stick was first invented by Michael M Rauhut and Laszlo J Bollyky based on the works on Edwin A Chandross. Glow Sticks are very important to the modern times because they affect the society, living conditions and the environment.

reaction rate increases. If the temperature of an enzyme gets to high the reaction rate will slow
