The reaction 2 H2O2(aq) → 2 H2O(1) + O2(g) is first order in H2O, 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% H2O, 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 Oz forms in 85.0 seconds at a barometric pressure of 742.5 mmHg? (The vapor pressure of water at this temperature is 17.5 mmHg.)
