4. In the cobalt lab you manipulated the following equilibrium, Co(H2O)2+ (aq) + 4C1- (aq) + COCl - (aq) + H2O(l). (1) (20 points) Suppose that the above reaction is at equilibrium, but then you sud- denly add 10.0 mL of 1.0M HCl. In which direction would the equilibrium be shifted? (II) (10 points) How will the addition of HCI affect the equilibrium constant for this reaction? Please explain with at least five sentences and no more than 10 sentences...

Several groups of general chemistry lab students measured the equilibrium constant for the same chemical equilibrium. In comparing their results, they found that they had different values because the temperatures of the experiments were different. Everyone was disappointed by the inconsistency, except for Dexter when he realized the measurements were made at different measured temperatures: "My esteemed colleagues," he said, "together we have sufficient data to determine two additional thermodynamic parameters and show the lab instructor what we know!" What...

I am doing a lab on the determination of the equilibrium constant for the formation of Fe(SCN)+2. We used a spectrometer to measure the absorption of solutions with a varying initial concentration of Fe+3, but constant concentrations of SCN-. The reaction equation of Fe+3 + SCN- —> Fe(SCN)+2. Along with the SCN- and Fe+3 stock solutions, we also combined them with .3 M HNO3. We then calculated an average molar absorptivity and the equilibrium concentration of Fe(SCN)+2. From that concentration...

Question 24 6 pts You do not need to type out your answer to this question. Please write it on your written work paper. Lactic acid (HC3H30) is a waste product that accumulates in muscle tissue during exertion, leading to pain and a feeling of fatigue. The balanced chemical equation for the reaction that occurs when lactic acid is dissolved in water is shown below: HC,H,O3 (aq) + H2O (1) + C3H4O3 (aq) + HO* (0) a. Write out the...

I just did a lab on determination of an equilibrium constant through the reaction EtAc (aq) + H2O (sln) <-> EtOH (aq) +HAc (aq). For all initial concentrations, K was less than one. Which I know says that equilibrium favors reactants. One of the post lab questions is "Is the hypothesis that the equilibrium constant, K, really a constant not dependent on the initial concentrations correct? Explain your answer. " I am not sure how to answer this
