Hydrogen peroxide is made by white blood cells to destroy harmful bacteria. When hydrogen peroxide decomposes, it forms molecular oxygen and water. 2 H2O2(aq) ⟶ O2(g) + 2 H2O(g) Suppose O2 is being formed at a rate of 0.65 M/min. At what rate (M/min) is the concentration of hydrogen peroxide changing? Enter your answer to 2 decimal places.
