3. The reversible reaction of thymol blue with ammonium chloride is shown in the image below. In this reaction C27H29O$S¯ (which is yellow when dissolved in water) reacts with NH4CI to produce C27H29O5SH (which is blue when dissolved in water) and NH3 (aq). When the reaction is at equilibrium the solution is a green color. C27H2905S- (ag) + NH,CI (aq) > C27H2905SH (ag) + NH3 (aq) Yellow Blue Reaction after it reaches equilibrium appears Green a. Why is the solution green at equilibrium? Answer this question in a complete sentence that demonstrates your understanding of equilibrium. because at eaui irbrium b. When the reaction is heated the reaction changes color, becoming green-blue, and after 5 minutes of heating it becomes dark blue. Is the reaction endothermic or exothermic? Use Le-Chatlier's principle to explain how you arrived at your answer. Your response should be formatted as complete sentences in paragraph format. c. Draw a reaction diagram for the reaction between C27H29OSS¯ and NH4CI. Label the enthalpy, activation energy, reactants and products. d. Make a prediction for each of the following disturbances to equilibrium for the reaction between C27H29OSS and NH4CI. Assume the reaction mixture is at equilibrium, appearing green in color, and at room temperature before each of the following disturbances.
