Recall that the unit for the rate constant is given by:
The given rate constant only has s–1 as its units, which means n = 1 and the reaction follows first-order kinetics.
The integrated rate law for a first-order reaction is as follows:
For the decomposition of gaseous dinitrogen pentoxide,
2N2O5(g) ⟶ 4NO2(g) + O2(g)
the rate constant is k = 2.8 x 10-3 s-1 at 60°C. The initial concentration of N2O5 is 1.58 mol/L.
(a) What is [N2O5] after 5.00 min?
