N2O5 decomposes according to the equation, N2O5(g)→2NO2(g)+12O2(g)
This is a first order reaction. A closed container has N2O5 and Ne gases at a total pressure of 333.8 mm of Hg. Thirty minutes after N2O5 starts decomposing, the total pressure is found to be 384.5 mm Hg. On complete decomposition of N2O5, the total pressure is 684.5 mm Hg. What is rate constant of decomposition of N2O5?
(Take ln(1.169) = 0.156)
