Hydrogen peroxide, H2O2, decomposes according to the equation above. This reaction is thermodynamically favorable at room temperature. (a) A particulate representation of the reactants is shown below in the box on the left. In the box below on the right, draw the particulate representation of all the molecules that would be produced from these four reactant molecules. O=0 = H 2 H2O2 (aq) 2 H20(1) + 02 (9) (b) Shown below is a potential energy diagram for the uncatalyzed decomposition of H2O2 (aq). 2 H2O2 2 H20 + O2 Reaction Progress (i) According to the diagram, is the decomposition reaction exothermic or endothermic? Justify your answer. Potential Energy (ii) Manganese dioxide, MnO2 (s), is an insoluble substance that acts as a catalyst for the decomposition reaction. On the diagram above, draw a curve to represent the reaction as it occurs in the presence of MnO2 (s). 1 Upload files (PDF, JPG, GIF, PNG, TXT, Word, Excel, Powerpoint, file formats supported) 0/2 File Limit
