Answer:

1- Adding Br₂ increases the concentration of Br₂, causing the reaction progress to shift to the left (away from the NO).

2- Adding BrNO increases the concentration of BrNO, causing the reaction progress to shift to the right.

Explanation:

  • To solve this question, we should mention Le Chatelier's principle states that if we affect on an equilibrium by an external factor, the reactions shifts to the direction that can suppress the effect of the external factor.
  • 1- the effect of adding additional Br₂(g) to the reaction mixture:

Adding Br₂ increases the concentration of Br₂, causing the reaction progress to shift to the left (away from the NO).

Adding Br₂, increases the concentration of Br₂, so the reaction shifts to the reactants side (left) to cancel the increase in Br₂ concentration.

  • 2- The effect of adding additional BrNO:

Adding BrNO increases the concentration of BrNO, causing the reaction progress to shift to the right.

Adding BrNO, increases the concentration of BrNO, so the reaction shifts to the products side (right) to cancel the increase in BrNO concentration.
