Thank you for the opportunity to help you with your question!
makes no difference whether you increase 5times the volume after at the
equlibrium established in (1) of you start start the reaction from
initial pure nitrogen dioxide in a 5times bigger volume flask.
increasing the volume 5 times original means halving the initial pressure to
so normal atmosphere pressure= 29.92 in Hg
so initial pressure becomes = 29.92/5 =5.984
The partial fulfill equilibrium condition:
Kp = (p(NO2))² / p(N2O4)
Kp = (p₀ - 5·Δp)² / Δp
now we have Kp=0.26 and p0=5.984
now find out Δp
0.26 = p0^2 +25 Δp^2 -1op0 Δp
25 Δp^2 - 10.26 p0 Δp + p0^2=0
25 Δp^2 - 61.4 Δp +35.81 =0
find the value of Δp
Please let me know if you need any clarification. I'm always happy to answer your questions.
