Solution

The correct options are
A Amount of $N_{2}$ gas will increase
C Amount of $O_{2}$ gas will decrease
When some amount of $H C l$ is added to equilibrium, the first equilibrium will be shift in backward direction leading to decrease in amount of $O_{2}$ .

Then, the second equilibrium will shift in backward direction to increase the amount of $O_{2}$ . Thus, amount of $N_{2}$ gas will increase.
