91. A common demonstration in chemistry courses involves adding a tiny speck of manganese(IV) oxide to a concentrated hydro- gen peroxide (H₂O₂) solution. Hydrogen peroxide decomposes quite spectacularly under these conditions to produce oxygen gas and steam (water vapor). Manganese(IV) oxide is a catalyst for the decomposition of hydrogen peroxide and is not consumed in the reaction. Write the balanced equation for the decomposition reaction of hydrogen peroxide. 92. Iron oxide ores, commonly a mixture of FeO and Fe,O,, are given the general formula Fe,O,.

Suppose a pair of chemical compounds A and B can react in two different ways: A+B C Reaction 1 gives product C. A+B D →> Reaction 2 gives product D. The following facts are known about the two reactions: • Reaction 1 is endothermic and Reaction 2 is exothermic. • If a reaction vessel is charged ("filled") with A and B, then at first C is produced faster than D. Use these facts to sketch a qualitative reaction energy diagram for both reactions. Note: because these sketches are only qualitative, the energies don't have to be exact. They only have to have the right relationship to each other. For if one energy is less than another, that fact should be clear in your sketch. energy A + B Reaction 1 reaction coordinate energy A + B Reaction 2 reaction coordinate ☑
