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:

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.

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.
