The rate law

The N2O decomposition reaction is represented by the following equation:

2 N2O(g) → 2 N2(g) + O2(g)

This reaction is first order, and k = 3.40 s-1 at a certain temperature.

In an experiment at the same temperature, the initial concentration of N2O is 0.27 M. Determine how many seconds for the initial 50% decomposition of N2O: t =____ second
