Removing NO or Br2 would shift the reaction to the right because changing the concentration of an ingredient will shift the equilibrium to the side that would reduce that change in concentration. A decrease in pressure due to increasing volume causes the reaction to shift to the side with more moles of gas. There is no effect on a reaction where the number of moles of gas is the same on each side of the chemical equation. Therefore, increasing volume will have no effect. Answer: A. Decrease in temperature As the reaction is endothermic (delta H is positive), increase in temperature increases the K value hence according to Le-Chatelier\'s principle, to reduce the change in K to normal, reaction shifts to the left. .
