Chemical equilibrium

speed at which the chemical reaction is taking place (Merriam-Webster). There are many factors that can affect the rate of a reaction, such as adding heat to speed up the reaction rate, removing heat to slow it down, change in concentration, and the particle size. A reversible reaction is a reaction in which reactants form products. This theory was initially introduced by French chemist Claude Louis Berthollet in 1803 (Encyclopedia Britannica). If a reaction is in equilibrium, then it is making products

presence of enzymes can change the rate of reaction. An enzyme is a specialized protein that catalyzes chemical reactions (Freeman, et al, 2014,p.46). If a reaction occurs the reactants must interact with a specific orientation and there must be enough kinetic energy to reach the activation energy required for the reaction (Freeman, et al, 2014, p.55). Enzymes are an important part in chemical reactions because they move the reactants together in the orientation needed for the electrons to interact

effects of NaCl on Catechol Oxidase Activity Abstract Enzymes quicken chemical reactions in a cell. This experiment was performed in order to determine if adding NaCl to an enzyme would have an effect on the rate of the reaction of the enzyme. It is said that salt inhibits the reaction the reaction rate of enzymes. It can inhibit reactions making the protein unstable or by also messing with the equilibrium constant of the substrate being catalyzed. In our experiment tube 1 consisted of

Given that equilibrium prices and profits of two retailers are known, consumers’ bias and the influence of the dealer costs on retailers’ pricing and profit condition will be discussed in four contexts: When a + b < 1 and c1 < c2, that is, consumers may like shopping in MCRs retail stores while costs of MCRs retailers are higher than that of Dotcoms retailers, MCRs retailers now have priority from aspects of consumers’ preference, and Dotcoms retailers are superior to MCRs in term of costs. a +

the equilibrium concentrations of products and reactants in several organic reactions, involving acetic acid, methanol, methyl acetate, and water. The acid and alcohol react to form an ester and water, and the ester hydrolyzes to produce the acid and alcohol3. These reactions continue in the forward and reverse directions until equilibrium is achieved. The equilibrium constant, K, is a measure of the relation of the activities between products and reactants in a reaction, in which the chemical potential

utopia. Each and every animal on the farm is regarded to be equal. There was no more human tyranny, but instead a communal and democratic society where one animal had just as much social influence as the next. Libria, depicted in Kurt Wimmer’s film, Equilibrium, is yet another example of the elimination of a hierarchy. People dressed in the same clothes, lived in the same houses, and felt the same things. There was no variation, just a single class: human. This seems simple, but how could this ever be

Equilibrium 7022 April 24th 2015 CHM 2046 – 032   Introduction Equilibrium is the state where the concentrations of the reactants and products are equal, or unchanging . By adding more of a product or reactant can change the direction of the reaction, altering the equilibrium of the reaction (Tro). The equilibrium constant (K_eq) is a ratio of the concentrations of products over the concentrations of reactants (Tro). The equilibrium constant helps to quantify the extent to which direction the

solubility, to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically, the goal of this experiment is to prepare a saturated solution of Na2C2O4 in water at different temperatures, determine the effect of temperature in solubility, and to apply Le Chatelier's Principle. We can do all this by simply titrating a certain amount of standard KMnO4, and measuring how much KMnO4 was needed to help Na2C2O4 reach chemical equilibrium at certain temperatures

FeSCN2+. To answer this guiding question, Le Chatlier’s principle, volume, absorbance, and concentration all effect outcomes of equilibrium. For this reason, all three components will be collected in order to solve for the average formation constant. Equilibrium is the rate at which the forward reactions and reverse reactions become equal at a constant rate. Equilibrium constant, denoted by K, is the relationship between the concentrations of product over the concentrations of reactants raised to
