Chemical and Ionic Equilibrium 1 Question 18
19. At constant temperature, the equilibrium constant for the decomposition reaction, $\mathrm{N}{2} \mathrm{O}{4} \rightleftharpoons 2 \mathrm{NO}{2} K{p}=\frac{4 x^{2} p}{\left(1-x^{2}\right)} p= x=$ extent of decomposition. Which one of the following statement is true?

Solution:
- $\underset{1-x}{\mathrm{~N}{2} \mathrm{O}{4}} \rightleftharpoons \underset{2 x}{2 \mathrm{NO}{2}}, K{p}=\frac{4 x^{2} p}{1-x^{2}} \cdot K_{p}
p x$.
