Study carefully the reaction represented by the equation below. 2H2O 2(l) → O 2(g) + 2H2O(l). Which of the following will not reaction increase the reaction rate?
Heating the hydrogen peroxide
Adding a pinch of MnO2 to the reactant
increasing the concentration of the H2O2
Adding water to the reactant
Exposing the reactant to sunlight
Correct answer is D
Reaction of decomposition of hydrogen peroxide is very slow in moderate temperatures without the presence of a catalyst.
It can be sped up by increasing the temperature, which triggers the reaction of thermal decomposition.
