$N_{2} O_{4} (g) ⇌ 2 N O_{2} (g)$ is $1/3$ dissociated at a total pressure of 8 atm. At what total pressure (in atm) will it be 50% dissociated at the same temperature?

Answer:

Solution:

$K_{P} = 4 α^{2} P / (1 - α^{2}) = 4 (1/9) (8) / (8/9) = 4 atm$ .

At $α = 0.5 : 4 = 4 (0.25) P /0.75 = (4/3) P$ , so $P = 3 atm$ .

Answer: 3.
