They are very stable. they have a "full table" so to speak. they have no valance electrons. they do not give electrons and they do not take them either. there are very few if an elements that can be paired with noble gasses

Explanation:
As the given reaction equation is as follows.
![N_{2}(g) + O_{2}(g) \rightleftharpoons 2NO(g)](https://tex.z-dn.net/?f=N_%7B2%7D%28g%29%20%2B%20O_%7B2%7D%28g%29%20%5Crightleftharpoons%202NO%28g%29)
Hence, expression for
of this reaction is as follows.
Now, putting the given values into the above expression as follows.
=
= ![5.05 \times 10^{-2}](https://tex.z-dn.net/?f=5.05%20%5Ctimes%2010%5E%7B-2%7D)
Thus, we can conclude that the value of
is
.
