Question

Hydrogen peroxide, H2O2(aq), must be stored at low temperatures to reduce the rate at which it decomposes to water and oxygen. The decomposition reaction is shown in the equation below: 2H2O2(aq) -> 2H2O(l) + O2(g) A student wants to investigate the rate of decomposition of H2O2(aq) at room temperature and pressure. They set up an experiment that will measure the volume of oxygen gas produced over time. The student uses 30.0 cm^3 of 2.50 mol/dm^3 H2O2. The student collects results at a series of time intervals and uses that data collected to determine the concentration of H2O2(aq) at each time. They then use this data to plot a concentration-time graph as shown in figure 4. Figure 4: Concentration-time graph for the decomposition of hydrogen peroxide Determine the number of moles of oxygen that have been produced throughout the duration of the experiment.
