Equilibrium Essay

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

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 this experiment, the equilibrium properties of

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

A system is at equilibrium when the forward rate of reaction is equal to the reverse rate of reaction (UNC, 2016). In cuvettes E1-E5, a chemical equilibrium is reached based on the reaction: Fe^(3+) (aq)+SCN^- (aq)↔FeNCS^(2+) (aq) One can be sure that the system is at equilibrium in these five cuvettes because there are concentrations of both reactants and the product when the cuvettes stop changing color (Table 2). If the system were not at equilibrium, one of these three substances would have reached

to be a 6. percent error. 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

In chemistry, equilibrium occurs when both the reactants and products in an equation are present in concentrations which have no further likelihood to change with time. Generally, this state results when the forward reaction proceeds at the same rate as the reverse reaction. Concentration, pressure and temperature are factors that can affect the equilibrium state of a reaction (Source). In 1803, the concept of chemical equilibrium was developed after Berthollet discovered that some chemical reactions

PART A A reaction at equilibrium means that both the forward and the reverse reactions occur at equal rates. This means the reactants and products in the reaction will stay unchanged in its composition as long as nothing disturbs the system. If the O2 concentration increases, the reaction shifts to the right side to use up more O2 by combining it with the Hb, resulting in more HbO2. If the HbO2 concentration increases, the reaction shift to the left side to break down the HbO2 and increase the

Chemical equilibrium is a dynamic state where the rate of the reverse reaction is equal to the rate of the forward reaction. The chemical reaction is still occurring however the rate of reverse reaction is matching the rate of forward reaction hence the concentration of reactants (〖Hb〗_((aq) )+ O_(2 (g))) and products (HbO_2) no longer change, resulting in an equilibrium. (b) Which direction will equilibrium shift if the O_(2 ) concentration is increased? Higher concentration of O_(2 ) will result
