The reaction 2H2O2(aq)→2H2O(l)+O2(g) is first order in H2O2 and under certain conditions has a rate constant of 0.00752 s−1 at 20.0 ∘C. A reaction vessel initially contains 150.0 mL of 30.0% H2O2 by mass solution (the density of the solution is 1.11 g/mL). The gaseous oxygen is collected over water at 20.0∘C as it forms. What volume of O2 will form in 43.4 seconds at a barometric pressure of 735.9 mmHg . (The vapor pressure of water at this temperature is 17.5 mmHg)
