The decomposition of N2O5 proceeds according to the following equation
2 N2O5(g) → 4 NO2(g) + O2(g).
The rate constant, k, for the reaction at 298 K is 2.20 x 10-3 min-1. If a reaction is set up in a vessel at 298 K, with an initial concentration of 0.343 mol L-1; what is the concentration of reactant N2O5(g) in mol/L after 42 minutes?
