Determination of an equilibrium constant essay

Furthermore, writing the equations for the reactions and apply the rules of solubility to see if every color change equals to a precipitate. Conclusion Since equilibrium constant cannot be easily affected by physical factors, except for temperature.

Determination of an Equilibrium Constant Essay

It is possible to measure the ethanoic acid by titration with standard NaOH which remove ethanoic acid and catalyst hydrochloric acid without significantly disturbing the equilibrium position.

Examining the Solubility of Substances in Double Also if we shake it too vigorously, this will increase kinetic energy of chemicals and affects Kc Improvement: The reaction is slow enough at room temperature so that the orders of mixing, temperature fluctuations over two days of reaction time, and even a final titration with a strong base have little effect on the reaction.

The one used in this experiment is titrimetric one since the hydrolysis is kinetically slow. The aim of this experiment is to compare the rate of reactions of the reaction of yeast with the three different carbohydrates, namely glucose, sucrose, and lactose.

Spectrophotometric Determination of Equilibrium Constant

Hence equilibrium of a reaction can be obtained by many methods, e. The aim of this investigation is to perform various double replacement reactions with known substances and record the qualitative observations. Due to some measuring error, the amount of HCl is not the same so equilibrium amount of ethanoic acid obtained are not accurate which in turn affect Kc Improvement: The value of k, the rate constant will also be determined for this reaction at the temperature room temperature at which the experiment was conducted Since the reaction is kinetically slow even in the presence of the catalyst.

The equilibrium position will shift rightward, producing more products so as to reduce more reactant.

Dependent Volume of gas produced in 3 minutes measured by the graduated glass collecting tube Using a graduated glass collecting tube. The rate of reaction should be fastest in the reaction between yeast and sucrose, since sucrose is broken down to two molecules of glucose, thereby giving more glucose for the yeast to act on.

Two hypotheses were established based on my research question: Prior to proposing a possible mechanism for the reaction that is consistent with the suggested rate equation. Addiction of water, which in turn pushes the equilibrium shifting to the right so as to remove the additional water.

Furthermore, one of the products is removed due to the neutralization of the equilibrium mixture with sodium hydroxide. It is predicted that a solid will form only when there is a change in color.Determination of an Equilibrium Constant.

CH – Chem 2 Lab Determination of an Equilibrium constant Goals The purpose of this experiment is to determine the equilibrium constant for the reaction Fe3+(aq) + HSCN(aq) –>FeSCN2+(aq) + H+(aq). Spectrophotometric Determination of Equilibrium Constant.
