first-order decomposition of dinitrogen pentoxide

In the first-order decomposition of dinitrogen pentoxide at 335 K, assume we start with a 2.50 g sample of N2O5 at 335 K and have 1.50 g remaining after 109 s.
N2O5 (g) -----> 2NO2 + 1/2 O2
(a) What is the value of the rate constant k? (in s^-1)
(b) What is the half-life of the reaction? (in s)
(c) What mass of N2O5 will remain after 5.0 min? (in g)

Solution Summary
