DATA ANALYSIS The linear relationships between the time elapsed and the volume of gas indicates a constant enzyme reaction rate. The activity rate of catalase in figure 1 is calculated to be approximately 0.15mL/sec. The following figures show how this rate of reaction is affected by different external factors. The results in figures 2 and 5 show an increase in either enzyme concentration or substrate concentration will increase the enzyme activity. In figure 2, the 0.75% enzyme concentration…

(RFV) process based on the knowledge that the catalyst bed is preheated to high temperature, pyrolysis of the heated cellulose particles on the surface of the bed is expected to be fast enough that it will not be a rate-limiting step. Hence, the kinetics of the RFV of cellulose reduces to gasification of the produced volatile organic compounds (VOCs) on and in the catalyst bed. To represent the RFV of the VOCs from flash pyrolysis of cellulose, Aspen Plus has been used as the primary modelling…

There a five ways to speed up reaction rates. The first is to get the particles moving faster, this is done by heating up the particles, giving them more kinetic energy. The second is to increase the surface area, increasing the likelihood in which the particles will have contact with each other because it now has a greater surface area, this can be achieved by breaking down solids. The third is concentration…

Breaks are not something people take the time to think about. Even if they are fundamental to the vehicles many people use every day. The functionality of breaks is contributed to physics and engineers ability to understand that physics. There is a lot going on when people press on the brake pedal in their car. The most basic principle of brake pads is in fact friction. This friction is the thing that transfers the energy of the car moving forward to heat energy. Brakes also use pressure as a…

A. Defining Reaction Mechanisms and Catalyst Structure The methane-to-methanol reactions that we aimed to evaluate consist of four critical steps starting from the initial reactants (CH4, NH4+, oxo): C-H activation followed by a hydrogen atom abstraction (HAA) from CH4 to form some combination of the hydrogenated complex, ammonium or ammonia, and a methyl radical; a radical rebound (RR) to form a methanol adduct and ammonium; methanol dissociation from the metal; and catalysis regeneration via…

Physics can often explain many of the everyday activities of life; from playing football to ice skating to visiting an amusement park. Most people step into an amusement park excited for the thrill of riding all of the roller coasters without ever giving any thought to the physics behind the ride. There are several components of physics which contribute to the thrill of roller coasters, including gravitational forces, the law of conservation of energy, friction, centripetal force, and normal…

Research Question: To compare the enthalpy change of reaction of 3 neutralization reactions by using 3 different acids of distinct pH. The same base of NaOH will be used in all three experiments. Introduction: Chemical reactions always have energy change. Energy in the form of heat, if liberated is known as exothermic and if absorbed in the reaction is known as endothermic. When a reaction carried out under standard condition at a of temperature 298K and 1 atm of pressure and 1 mole of water…

The TG and DTA curves obtained for the compounds (C1-C5) are shown in Figure 9. Table 4 lists the results of the thermal studies of these compounds with the initial and final temperatures (ºC), assignments of each decomposition stage based on mass calculation and DTA peaks. These assignments (Δm - Calcd.) are based on the structural fragments from the theoretical formulae of the compounds (C1–C5). This implies that the groups proposed in the right column of Table 4 are not necessarily the…

Determination of Isoprenaline Hydrochloride Concentration Using Ultra Violet/ Visible Spectroscopy and Quantification of Sodium and Potassium Using Flame Spectroscopy Introduction In UV/VIS (ultraviolet-visible light) spectroscopy, light absorption as a function of various wavelengths gives data about electronic transitions within a solution [1]. The electronic transitions involve exciting an electron from one principle quantum state to another by the absorption of energy [2]. A change in…
