Chemical equilibrium

Abstract: For this experiment we are looking to determine the equilibrium constant KC for this reaction, KC = [FeSCN2+]/([Fe3+]•[SCN-]. Using a spectrophotometer, we are going to determine the absorbance of FeSCN2+ with different concentration measurements. Introduction: Chemical equilibrium can be determined using different methods. Chemical equilibrium exists when the rate of both sides are equal. Once equilibrium has been reached, the amounts of products and reactants are constant, but if one

Introduction: During an enclosed chemical reaction, “chemical equilibrium” is the state in which both reactants and products are at a constant concentration that has no further intention to change. This state results in the forward reaction proceeding at the same rate as the backward reaction. The concepts of chemical equilibrium came about in 1803 by finding that some reactions are reversible. Therefore, the rates of the forward direction are directly proportional to the reverse reaction rate. In

Once a reaction has reached its chemical equilibrium it consists of a point where the rates of the forward and reverse direction of a reaction equal each other. Since at this point there is no movement that needs to take place the chemical process can be considered to be stabilized. When a reaction has reached equilibrium, the reactants become products and the products decompose into the reactants at the same rate (Gas-Phase, 2014). In other words, the forward reaction must occur at the same rate

Background A chemical equation that is in equilibrium will naturally balance itself out should either the products are the reactants be increased, or other stresses such as temperature and pressure are placed on it. However, as with a lever in physics, the fulcrum or balancing point is not always in the middle. In most cases, one side of the equation will be favored more. Ergo, the equation will try to balance to this point of equilibrium. Materials We did several different examples of chemical equilibriums

Chemical Equilibrium Ben Cooper TA Kia Williams CHM2046l.004 20 April 2015   Introduction Chemical equilibrium is defined as “a state in which the rate of the forward reaction equals the rate of the backward reaction” [1]. Equilibrium constant, defined as “a number that expresses the relationship between the amounts of products and reactants present at equilibrium in a reversible chemical reaction at a given temperature” [2]. The equilibrium constant, Keq, was found by multiplying the products’

iron(III) (Fe3+) and thiocyanate (SCN-) formed, which was processed and now being communicated through the quantitative data collected. Chemical reactions are constantly moving forward towards the products side as well as in reverse towards the reactants side and at times when both are done shifting the reaction is said to have come close to “completion or equilibrium” (“Determining

Chemical Equilibrium Lab Report Aim: The aim of the lab “Chemical Equilibrium” is to observe the effects of changes in concentrations of products and reactants on the position of the equilibrium of given chemical reactions. Background Information: We are going to use our knowledge of the Le Chatelier’s principle in order to observe this experiment. The principle states that the equilibrium will shift in the direction that will minimize the effects of the change. This lab consists of two

Chemical Equilibrium Introduction     The goals of this experiment were to describe and understand what happens when a reaction reaches equilibrium. It was also done to understand what happens to the equilibrium when the variables are changed. There are different chemical species present in the following solutions. Fe(N. Fe(NO3) has Fe+2, NO3-, and H2O. In KSCN there is SCN-, K+ and H2O.Those mixed has the following chemical species, NO3-, SCN-, H2O, and Fe3+.  The equation ends up being FE3 + SCN
