Question

Using the law of mass action, derive the mathematical expression of the equilibrium constant for N₂(g) + O₂(g) ______ 2NO₂(g).

a) [NO₂]² / [N₂][O₂]
b) [NO₂] / [N₂][O₂]
c) [N₂] / [O₂]
d) [NO₂]² / [N₂]²[O₂]²

Answer 1

The equilibrium constant expression is [NO₂]² / [N₂][O₂].

Step-by-step explanation:

The equilibrium constant expression for the reaction N₂(g) + O₂(g) ⇌ 2NO₂(g) is represented by the mathematical expression [NO₂]² / [N₂][O₂] (option a).
