WebThe graph in Figure 18.1.4 shows the rate of the decomposition of H2O2 H 2 O 2 over time: 2H2O2 → 2H2O+O2 2 H 2 O 2 → 2 H 2 O + O 2. Based on these data, the instantaneous rate of decomposition of H2O2 H 2 O 2 at t = 11.1 h is determined to be 3.20×10−2 3.20 × 10 − 2 mol/L/h, that is: WebNov 1, 2012 · Signs that a chemical reaction has occurred.
