**Question 7**

Nitrogen and oxygen react to produce nitrogen monoxide according to the following equation:

\[ \text{N}_2 (g) + \text{O}_2 (g) \rightleftharpoons 2 \text{NO} (g) \]

The equilibrium constant (\( K_c \)) for this reaction is 0.0123 at 3900°C.

a. Write a \( K_c \) expression for this reaction.

b. What is the equilibrium concentration of each reactant and product in units of M (molarity) if an 8.00 L vessel originally contained 0.195 moles of each reactant?
