The decomposition of hydrogen peroxide, 2 H₂O(aq) → 2 H₂O(l) + O₂(g), follows first-order kinetics with respect to -1 H2O2 and has k = 0.041 min in the rate law for the decomposition of H₂O2. If the initial concentration of H₂O2 is 0.35 mol/L, what is its concentration after 42 min? Answer in units of mol/L. How much time will it take for the H₂O₂ concentration to decrease from 0.5 mol/L to 0.21 mol/L? Answer in units of min. How much time will it take for the H₂O2 1, concentration to decrease by =? Answer in units of min. How much time will it take for the H₂O2 concentration to decrease by 83%? Answer in units of min.
