Answer:
At equilibrium, reactants predominate.
Explanation:
For every reaction, the equilibrium constant is defined as the ratio between the concentration of products and reactants. Thus, for the reaction N2 (g) + O2 (g) ⇌ 2NO the expression of its equilibrium constant is:
![Keq = \frac{[NO]^{2}}{[O_{2} ][N_{2}]}](https://tex.z-dn.net/?f=Keq%20%3D%20%5Cfrac%7B%5BNO%5D%5E%7B2%7D%7D%7B%5BO_%7B2%7D%20%5D%5BN_%7B2%7D%5D%7D)
Since the equilibrium constant is Keq = 4.20x10-31 the concentration of reactants O2 and N2 must be much higher than products to obtain such a small number as 4.20x10-31 at the equilibrium. Hence, at equilibrium reactants predominate.

➷ For scientific uses, the main key property is that gold is unreactive. Gold is naturally occurring and found in nature. It is highly unreactive. This is also a beneficial quality for industrial uses such as making jewelry. Gold has tarnish resistance and takes a lot longer to dull in color than many other metals. Also, Gold is highly ductile meaning it can be drawn into thin wires to create detailed and delicate jewelry.
