Reaction

A redox reaction is a type of reaction that results in the exchange of one or more electrons leaving one product oxidized and one product reduced. The product that becomes reduced gains an electron, and the product that loses an electron becomes oxidized. This process can be simply thought of as a chemical reaction where electrons are transferred. Redox reactions occur as a way to transfer energy in the form of electrons. This happens in several biological processes, including cellular…

rate of reaction on Enzyme reaction Introduction: This experiment will investigate the effect of temperature on the rate of reaction of the enzyme catalase. The biological catalyst called enzymes increase the rate of reaction without themselves being chemically changed. Enzymes are globular proteins folded into a complex 3-dimensional shape that contains a special surface area called the active site where a specific substrate binds structurally and chemically. Enzymes speed up reactions as…

In a biochemical reaction, enzyme which are proteins based compounds are used as a catalyst to produce a high yields. Proteins are the macromolecular components of almost enzymes, except for ribozymes, a class of RNA modifying catalysts. Enzymes are classified on the basis of their composition; simple enzymes are those composed wholly of proteins, whereas, complex enzymes which also known as haloenzymes, composed of protein plus a relatively small organic molecule. In this terminology the…

To improve the yield of the ester the reaction should be heated using a high temperature. This would favour the formation of the products in this reaction, as the formation of an ester (esterification) is an endothermic reaction. Thus use of a high temperature will push the equilibrium to the right hand side, and a larger yield of the ester will be produced. To improve the yield of the Ester the reaction mixture could be refluxed for longer period of time so that more reactants are converted…

Nucleophilic substitution Nucleophilic substitution reaction is that in which attacking nucleophile replaces a leaving group. Attacking nucleophile: specie with an electron free pair or negative charge and ability to replace already present nucleophile i.e OH- Leaving group: A specie with electron deficiency or positive charge, negative charge i.e Cl- What is SN1 Reaction:- SN1 indicates the unimolecular nucleophilic substitution reactions. Their rate determining step of the mechanism depends…

INVESTIGATE AN ASPECT OF REDOX SYSTEM/REACTION Research Question: Does a higher voltage lead to more mass on graphite? INTRODUCTION Hypothesis: Higher voltage leads to more mass amassed on graphite electrode. Electrolysis- the process in which electric current passes through a solution to effect a chemical change. In this case there is copper, copper sulphate and graphite. In a electrolysis there is an electrolyte which is the copper sulphate, the anode which is the graphite. This is the…

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 thus increase the rate of the reaction as well. The size and shape…

To demonstrate their effectiveness in creating new carbon to carbon bonds, the Grignard arylation of 2-butanone was carried out. The Grignard reaction of phenyl bromide and magnesium, followed by the addition of 2- butanone yielded a crude product of 2-phenyl-2-butanol. The 1H NMR spectra was taken before distillation, showing the crude product, as well as after distillation, showing one of greater purity. In addition, an IR spectrum was taken after distillation. Both the 1H NMR and IR spectra…

area on the reaction rate. Introduction: In this experiment the experimenters will seek to determine what factors determine the rate of a reaction with a catalyst. A catalyst is a molecule that starts a chemical reaction, but it is not part of the reaction it is causing. The experimenters will use pieces cut up potato as an organic catalyst. The potato contain enzymes that will perform the reactions. Enzymes, “are proteins, produced by living cells; they catalyze chemical reactions by lowering…

Chemical Reaction A Chemical Reaction is when there is change from physical reaction to nuclear reaction. In chemical reaction, there is also a change of a chemical substance to another, which in that case is the change to one or more productions. It 's when a substance changes and when you combine chemicals or mix them, you 'll most likely create a new one, not always but most of the time it will. Cooking food always involves a chemical reaction. It could be from baking a cake by mixing the…
