For the following reaction, the equilibrium concentration of NO2 is 0.38 M and equilibrium concentration of N2O₄ is 1.0M. What is the value of the equilibrium constant? 2NO2(g) ⇌ N2O₄(g)

Question

Quizplus · Accepted Answer

The equilibrium constant expression for the given reaction is Kc = [N2O4]/([NO2]²)
Substituting the equilibrium concentrations, we have:
Kc = (1.0) / (0.38)²
Kc = 6.9 (approx)
Hence, the answer is choice C.

For the Following Reaction, the Equilibrium Concentration of NO2 Is
