WebJan 11, 2024 · When an equilibrium constant is expressed in terms of molar concentrations, the equilibrium constant is referred to as Kc. The value of this constant at equilibrium is always the same, regardless of the initial reaction concentrations. This proportionality can be converted into an equation by including a constant. \[A … WebSpectrophotometric Determination of Equilibrium Constant Abstract The main purpose of the experiment is to obtain Keq's value of an unknown solution. It was obtained by means of a calibration graph by plotting the concentration of FeSCN2+ ions vs. its absorbance. Formed the best fit line acted as the graph of calibration.
WebIn this experiment we will study the equilibrium of the reaction: (1) Fe+ (aq) + SCN (aq) → FeSCN*2 (aq) The equilibrium constant expression for Reaction 1 is: = Keq [FeSCN2+1 (2) [Fe3+] [SCN-] When solutions containing the Fetion and the SCN ion are mixed Reaction 1 occurs form- ing the FeSCN2+ complex ion, which has a blood red color. WebOct 26, 2016 · Using this value, I used the equation for the K constant of an equilibrium: K = [ F e S C N X 2 +] [ F e X 3 +] [ S C N X −] K = 6.39 ⋅ 10 − 5 0.002 2 K = 15.975 This did not turn out to be the correct answer, but I'm not sure why. I suspect the concentrations for the two reactions are not correct since the volumes are also given. equilibrium
