Explanation:
Hello,
At first, the equilibrium constant should be computed because the whole situation is at the same temperature so it is suitable for the new condition, thus:
Now, the new equilibrium condition, taking into account the change x, becomes:
Nevertheless, since the addition of NO implies that the equilibrium is leftward shifted, we should change the equilibrium constant the other way around:
Thus, we arrange the equation as:
Finally, the new concentration is:
