he decomposition of nitrogen dioxide at a high temperature is second order in this reactant.
NO2(g) NO(g) + 1/2 O2(g)
The rate constant for this reaction is 3.40 L/mol·min. Determine the time needed for the concentration of NO2 to decrease from 2.30 mol/L to 1.30 mol/L.
[A] = [A]o + akt
Substitute the numbers and solve for t. a in this reaction is 1.
