Answer:
2N2O5 4NO2 O2
P            0                          0
(P-x) 2x x/2
0 2P P/2

Total Pressure after complete dissociation

5P/2 = 584.5

Pt = 233.8mmHg

Applying 1st order equation we have

K = 2.303/30 log [P]/[P-x]

= 2.303/30 log233.8/200
= 0.07log 1.16

~ 5×10-3

{ for calculation of "x" }

P-x+2x+x/2 = 284.5

x = 284.5 - 233.8 = 33.8 mmHg
