Due to our deviation being so low it indicates that the equilibrium constant is indeed a “constant”. Questions: In the lab it uses the definition equilibrium constant, what is meant when equilibrium constant is referred to, is the ratio of the molar concentrations of the reactants and products for the reaction. But in order for the ratio to be accurate the system must of reached equilibrium and temperature must have stayed constant. The value of Keq obtained from all our experiments was nearly
The movies “Blood Diamond” (2006), directed by Edward Zwick and “The Constant Gardener “(2005), directed by Fernando Meirelles, both focus mainly on the exploitation of Africa, especially by ‘The West’ and Europe. By highlight these important issues the movies awaken a sense of awareness in their audiences. In “The Constant Gardener”, Rachel Weisz was cast as one of the main Characters; Tessa Quayle. From the first memories Justin has of her in the conference room, Tessa is presented as a passionate
Determination of an Equilibrium Constant. Abstract: The report presents determination of equilibrium constant for the formation of a complex ion FeSCN2+. This was accomplished using a colorimeter to measure absorbance of some known concentration solutions in order to generate the calibration curve. The equation of the graph was used to compute the equilibrium concentrations of the reactants and products, needed to calculate the equilibrium constant for the reaction. I. Introduction:
Determination of an Equilibrium Constant Abstract: In this experiment, two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium, LeChatlier’s Principle, Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration
Justice is neither automatic nor inevitable; the attainment of justice typically entails the sacrifice and suffering of those attempting to achieve it. In essence justice is an ideal, which the majority of individuals universally attempt to realize or uphold, however due to the avarice or agendas, which serve the interests of minorities, this ideal is sometimes subverted. Those performing the miscarriage of justice can become unscrupulous in their methods of maintaining this standard of injustice
DATE PERFORMED: JULY 20, 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment, this spectrophotometry was used to determine the equilibrium constant, Keq, of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed, the concentration of the colored FeSCN2+ solution was also quantitatively
Programmatically Computing Mathematical Constants Many mathematical constants are useful for programming. For instance, if you need to use the transcendental number pi, you need to calculate it somehow. I set out to create a “library” of sorts to calculate as many mathematical constants as I could. Constant Explanation and Code Alladi-Grinstead constant The Alladi-Grinstead constant is defined as ec-1, where ck=21kln(kk-1). To do summation (), one has to use a for-loop with precision-limiting behavior
The Constant Gardener The Constant Gardener, which is one of the greatest movies I have ever seen, is not fiction. After watching the movie, if you search the title on the internet, you will know the shocking fact that this is a real story. The Constant Gardener originated from the novel The Constant Gardener written by John le Carré in 2001, based on a real-life case in Kano, Nigeria, related to medical experimentation in the 1990s. Therefore, both the novel and the movie are mainly depicting
The Strength of a Solutions is a three-part experiment. In part one of the experiment you had to determine the dissociation constant, Ka, of Acetic Acid. In order to do so, sodium hydroxide is titrated into a sample of acetic acid and the equivalence point is determined. Part two of the experiment consists of tested the dissociation constant. Acetic acid is mixed with sodium acetate. Part three of the experiment consists of adding acid or bases into the buffer solution and observing the changes that
Determining the Equivalent Mass and Dissociation Constant of an Unknown Weak Acid by Titrimetry Ka Chun Wong, and James Ross, Ph.D. East Los Angeles, Chemistry Department, 1301 Avenida Cesar Chavez, Monterey Park, CA 91754 Abstract Chemistry 102 is the study of kinetics – equilibrium constant. When it comes to the study of acid-base, equilibrium constant plays an important role that tells how much of the H+ ion will be released into the solution. In this lab, the method of titrimetry was performed
