Question 30

Chemical Equilibrium

N2O4(g) ⇌ 2NO2(g)
In the reaction above, the equilibrium constant is

  1. A.[NO2]/[N2O4]
  2. B.[2NO2]/[N2O4]
  3. C.[N2O4]/[NO2]2
  4. D.[NO2]2/[N2O4]
Show the answer and explanation

Answer: D ([NO2]2/[N2O4])

Explanation

K = [products]/[reactants], each raised to the power of its coefficient: [NO2]2/[N2O4].
