Question

one mole of N2O4 at 300k it kept in closed container under 1 atm it is heated upto 600k when 20% mass of N2O4 decompose to NO2 .Find the resultant pressure.........


answer fast

Answer 1

N2O4 → 2NO2

moles of unreacted N2O4 = 1 (1 - 0.2) = 0.8 

moles of NO2 = 2 * 0.2 = 0.4
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (+)
total moles n2 = 0.8 + 0.4 = 1.2

P1/(T1 n1) = P2/(T2 * n2)

1/(300 * 1) = P2/(600 * 1.2)

P2 = 2.4 atm

Hope it helps!!
