Chapter 12, Problem 12.37PAE

Again the experiment in Exercise 12.33 was redesigned. This time, 0.15 mol each of N, and O₂ was injected into a 5.0-L container at 2500 K, at which the equilibrium constant is 3.6 X 10^-?. What was the composition of the reaction mixture at equilibrium?

l'he following reaction establishes equilibrium at 2000 K:

N₂(g) + O₂(g) *2 2 NO
K = 4.1 X IO-4

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