Question
the Excel spreadsheet(s) and standard curve graph clearly showing the linear equation. Make sure your spreadsheet fits on a single sheet of paper!? Post lab questions (re-written and answered on a typed. separate sheet of paper) ost lab Questions 1. Explain what is meant by an equilibrium constant Was the value constant for all your experiments? Should it be constant? 2. What does the calculated experimental value of the equilibrium constant, Kc indicate regarding the degree of completeness of the reaction? In other words. at equilibrium, were there mostly products, reactants, or relatively large amounts of both? 3. When you use a spectrophotometer, should you set the wavelength of light to be the same color as that of the solution, or would a different color be more appropriate? Explain. 4. What was the color of light chosen for this experiment? What was the color of the MG complex ion?Explanation / Answer
An equilibrium constant of a chemical reaction is the value of the reaction quotient when the reaction has reached equilibrium. It can be anything as it depends on the ionic strength and temperature. It need not be constant for all the reactions.
The calculated value of Kc indicates the equilibrium constant at the equilibrium. At equilibrium you have equal mole fractions of the products and reactants
