ใครก็ได้ช่วยแนะนำวิธีทำหน่อยค่ะ(คร่าวๆก็ได้) กราบบบบบบบบบบบบบบบบบบบบบ

Dinitrogen pentoxide decomposes at 35°C with a first-order rate constant of
8 X 10-3 min-  according to: 2N2O5 ---->4NO2+O2
However, the product N02 rapidly dimerizes to N204
2NO2=N2O4
If the decomposition reaction is carried out in a constant volume at 35°C, plot
the pressure rise in the reactor as a function oftime, for an initial charge of pure
N20 S at 0.4 atm. Assume that the dimerization reaction equilibrates immediately.
The equilibrium constant of the N02 dimerization reaction at 35°C is
3.68. Assume ideal behavior.
