Chapter 12, Problem 12.41PAE

In the reaction in Exercise 12.33, another trial was carried out. The reaction began with an initial concentration of N₂ equal to the initial concentration of NO. Each had a concentration of 0.100 mol L-1. WTat were the equilibrium concentrations of all species?

The following reaction establishes equilibrium at 2000 K:

N₂(g) + O₂(g) ^2 NO
K = 4.1 X 10~4

If the reaction began with 0.100 mol L-1 of N₂ and 0.100 mol L'¹ ofO₂, what were the equilibrium concentrations of all species?
