А. Keq: [S03)(S02]
[NO][NO2]

B. Keq: [SO2)(NO2]
[SO3)(NO]

C. Keq: [SO3)3(NO]
[SO2)2(NO2)2

D. Keq: [SO3)(NO]

Answer:

D. Keq: [SO3][NO] /[SO2]NO2]

Explanation:

Hello!

In this case, according to the process to set up equilibrium expressions for chemical reactions at equilibrium, we realize we need to write up the concentration of products on top and that of reactants on bottom; thus, for there chemical reaction herein specified, we obtain:

[tex]Keq=\frac{[SO_3][NO]}{[SO_2][NO_2]}[/tex]

Thereby, the answer is D. Keq: [SO3][NO] /[SO2]NO2].

Best regards!
