3.2 Effects of particle size The particle size of the catalyst was highly influenced on the reaction rate, when the particle size of the catalyst was decreased, therefore their surface areas was increased and the ratio of catalyst surface and reactant volume was playing a crucial role for controlling the reaction kinetics. The reaction was takes place on the surface of a substance, increasing the surface area should increases the quantity of the substance that is available to react, and will…

Results and discussion 4.1 Material removal rate The material removed from each coupon was determined by measuring its mass before and after electro-polishing. Theoretical values were then obtained using Faraday’s laws of electrolysis as shown in Equation 9. (9) Where m is the mass of material removed in grams, I is the current and t is the electro-polishing time. EW is the equivalent weight which depends on the chemical composition of…

5.2.2.2 Interpretation of Regression Model The above equation can be written as D ∝ P^0.058/(V^(-0.117) 〖D_b〗^(-0.133) ) By observing the above equation we can say that the LAZ Depth is directly proportional to the Laser Power and inversely proportional to the Scan Velocity and Beam diameter. The observations of the model can be summarized as below: As Laser Power increases the LAZ Depth of workpiece surface will also increase. This is because the heat input to the workpiece is increasing…

The writing process is both complex and interesting at the same time. There are many ways to write and the process is different for everyone. In this essay, I will explain my found writing process and analyze my process alongside Peter Elbow’s Teaching Thinking by Teaching Writing, Alvarez’s Writing Matters, and Stafford’s A Way of Writing. My first step in writing begins with choosing the right location. Usually I choose my office or bedroom, but sometimes when I stick to a routine, I become…

the example equation below: Atomic Absorption Calibration Data We were asked to prepare a 10 g/L HCl solution from a 200 g/L standard solution, and found the volume by: Thus, we add 5 mL of 200 g/L HCl to get 100 mL of our 10 g/L HCl solution.…

CH 204 – Introduction to Chemical Practice Experiment 10 – Kinetics Joshua Fu* Tien Tran TA: Jamie Trindell April 25, 2016 INTRODUCTION This experiment focused on the concept of chemical kinetics, which describes the speed at which a chemical reaction occurs and the amount of reactant or product remaining after a specific period of time. Kinetics is important in analyzing the rates of certain species and reactions, and is a crucial technique to predict different reactions. Kinetics is…

investors will not pay for risk premiums, and defined by following stochastic differential equations: (1) (2) Where: S(t) represents the price process of an underlying assets. V(t) is the variance of the corresponding instantaneous returns. And the initial condition S(0), V(0) should be strictly positive. r is the risk-free return rate (non-negative…

The reaction between Propanone and iodine under acidic condition Aims To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation. Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction. General Method {For step by step guide of the experiment see preparation page} By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015…

Influenced through encounters with China and the West, the Japanese explored mathematical topics that were relevant to their time, which led to Japan’s shift from wasan (和算, Japanese Mathematics) to yôsan (洋算, Western Mathematics) in the Meiji era, and ultimately various technological advancements. As seen in Japan’s first encounters with the west, Sakoku (鎖国, the national seclusion policy) was the direct result of distrust of the Christian missionaries, which led to limited trade of ideas. In…

diluted with DI water and reacted to produce an unknown amount of FeSCN2+ ions in an equilibrium reaction. The absorbance of each solution was found using a spectrophotometer, the first five of which was used to create a calibration curve, whose equation relates the concentration and absorbance of FeSCN2+ ions. Theories…
