Solution: Consider the reaction 2 N2O (g) → 2 N2 (g) + O2 (g)    rate...

Problem

Consider the reaction

2 N2O (g) → 2 N(g) + O(g)    rate = k [N2O] 

Calculate the time required for the concentration of N2O (g) to decrease from 0.75 M to 0.33 M. The rate constant for the reaction is k = 6.8 × 10−3 s −1
