The recombination reaction 2 HO2(g) → H2O2(g) + O2(g) has a second-order rate constant of 1.7E9 M-1 s-1. Calculate the half-life of the reaction if the initial concentration of HO2(g) is 2.22E-11 M. Note: the coefficient 2 in the reaction means that the integrated rate law for this reaction is: 1/ct = 1/c0 + 2kt Give the answer to 3 significant figures
