What is meant by a state of ‘dynamic equilibrium'? What happens to the concentration of reactants and products when a reaction reaches a state of dynamic equilibrium? 2. The extent of reaction when the state of dynamic equilibrium is reached is given by the equilibrium constant for the reaction. Write down the equilibrium reaction and the expression for the equilibrium constant for the formation of FeNCS2+ from Fe3+ and SCN- ion. 3. What experimental method will be used in this experiment to evaluate the equilibrium concentrations of FeNCS2+? What is the color of the FeNCS2+ ion? At what wavelength is the concentration of the ion determined using Beer's law? 4. Calculate the concentrations of Fe3+ and SCN- in the reaction mixture in part I when you add 10.00 mL of 0.200 M Fe3+ to 1.00 mL of 2.0 x 10-3 M SCN- and make up the total volume to 50.00 mL? What is the concentration of FeSCN2+? 5. What are the concentration of Fe3+and SCN- in the reaction mixture in part III, when you add 5.00 mL of 2.0 x 10-3 M Fe3+ to 1.00 mL of 2.0 x 10-3 M SCN-and make up the total volume to 10.00 mL? How is the FeSCN2+ concentration determined for this part? 6. Why is the concentration of Fe3+ higher in part I compared to part III of the procedure?
