Question

What is the equilibrium constant for the reaction N₂(g) + O₂(g) = 2NO(g)?

A. Keq = [NO]² / [N₂][O₂]
B. Keq = [NO]²
C. Keq = [N₂][O₂] / [NO]²
D. Keq = 2[NO] / [N₂][O₂]

Answer 1

The equilibrium constant for the reaction N₂(g) + O₂(g) = 2NO(g) is Keq = [NO]² / [N₂][O₂].

Step-by-step explanation:

The equilibrium constant for the reaction N₂(g) + O₂(g) = 2NO(g) is given by the expression Keq = [NO]² / [N₂][O₂]. Therefore, the correct answer is A. Keq = [NO]² / [N₂][O₂].
