Chapter 12, Problem 12.40PAE

1’he reaction in Exercise 12.33 was repeated. This time, the reaction began when only NO was injected into the reaction container. 110.200 mol L_l NO was injected, what 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"' ofO₂, what were the equilibrium concentrations of all species?
