C2,H2905S- (aq) + NH,CI (aq) → CH2905SH (aq) + NH3 (aq) Yellow Blue Reaction after it reaches equilibrium appears Green A. Assume the reaction mixture is at equilibrium, appearing green in color, and at room temperature before each of the following disturbances. Explain which direction the reaction shifts to re-establish equilibrium and predict how the color of the solution will change 1.100 mL of water, H2O is added to the reaction mixture. 2. Solid platinum, Pt, is added to the reaction mixture. It reacts with NH3 to form N and H2 gasses. B. When the green reaction mixture at equilibrium is heated the color changes to green-blue, and then eventually, a dark blue color. When the green reaction mixture at equilibrium is placed in an ice water bath the solution color changes to a yellow-green, and eventually a bright yellow color. Is the reaction exothermic or endothermic?
