Factors Influencing Rate of Reaction Aim To investigate several effects believed to influence rate of reaction‚ concentration of a substance and temperature‚ and observe the effects. Hypothesis Concentration and temperature will both increase the rate of reaction in accordance with collision theory. Introduction The reaction rate or rate of reaction for a reactant or product in any given reaction can be defined as the speed with which a reaction occurs. For example‚ the oxidation of iron

that Affect the Rate of a Reaction BACKGROUND: Chemical reactions occur at different rates. In this experiment I will consider some of the key factors that influence the rate of a reaction: * nature of reactants - particle size * temperature * catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the

MY OJT EXPERIENCE I learned a lot from my experiences as an On-the-Job Trainee of Aboitiz Power‚ Therma Mobile Inc. First of all‚ I’m very much gratified for the support and understanding of my superiors especially on times when I committed mistakes. More than any learning thought in school‚ I learned to be with others‚ to work with people. I learn also to listen to my senior‚ Mr. Balali even though at times I can’t understand his instructions. I also learn to accept criticism and be apologetic

Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life. Enzymes are catalyst for biochemical reactions; Enzymes lower the activation ATP so a reaction can begin over the energy barriers. In this lab‚ a discussion of the enzymes reaction to heat will be addressed. Does heat speed up the enzyme reaction? The prediction is as more heat is applied more reactions will occur then at some point the heat will denature the enzyme as it reaches too

The Effect of the Concentration of Sulphuric Acid on the Reaction Rate with Magnesium Sarah Cain SCH 4UB Mr. Lankin April 1‚ 2009 Introduction The nature of the problem is to design an investigation that examines a variable affecting the reaction rate. In this experiment‚ magnesium will be reacted with different concentrations of sulphuric acid. The reaction is shown by the following chemical equation: H2SO4 (l) + Mg (s) → MgSO4 (aq) + H2

The purpose of the experiment was to perform an electrophilic addition reaction by the bromination of cinnamic acid. The product of this reaction is 3-Phenyl-2‚3-dibromo propionic acid‚ which is purified by recrystallization. Cinnamic acid (3-phenylprop-2-enoic acid) is an unsaturated carboxylic acid. The electron rich π cloud (see Figure 1) in the double bond of this structure is nucleophilic and can be considered a Lewis base. It can therefore be saturated by the addition of a halogen to the double

Introduction “The Enzyme Reaction” An enzyme is a protein that acts as a catalyst‚ which brings out a biochemical reaction. A Catalase enzyme‚ the enzyme tested in this experiment‚ is found in almost all living organisms that are exposed daily to oxygen (such as fruits‚ vegetables and animals). Background Information The Catalase enzyme in this experiment is known for being less affective the warmer the temperature is. According to “Science fair projects” an enzyme becomes unstable

hypothesis proposed that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min
