Problem

The reaction 

N2O3(g) → NO2(g) + NO(g)

is first order with a rate constant k = 0.0914 s −1. If a container is filled with N2O3 to a partial pressure of 0.87 atmospheres, how long will it take for the N2O3 partial pressure to fall to 0.63 atmospheres?

a) 87 s

b) 3.5 s

c) 21.6 s

d) 6.8 s

e) 76 s
