Consider N2O4 (g) ---> 2 NO2 (g) . 3.00 X 10-2 mol of N2O4 are placed in a 1.0 L flask. AT equilibrium, 2.36 X 10-2 mol of N2O4 remain. What is the Keq for this reaction?
N2O4 (g) ---> 2 NO2 (g)
Initial 0.03 molar 0
Change -x x
At equilibrium 0.03-x x
Keq = [NO2]^2 / [N2O4]
Given :
[N2O4] = x = 0.0236 molar
so [NO2] = 0.03- 0.0236 = 0.0064 molar
so Keq = 0.0064 / (0.0236)^2 = 11.49
