Question
Exothermic 1. Fill in the following table for endothermic and exothermic reactions: Endothermic n no so Absorb or release heat Positive or negative AH Products or reactants have higher energy Products or reactant more stable Favorable or unfavorable Bonds stronger in reactants or products 2. Circle the compound in each pair that has the higher bond dissociation energy/stronger bond: a. NH3 or PH3 b. H2Se or H2S с. CH4 or SIH4 Use AH and the balanced equation below to answer question 3 C,H12O6→ 2 C;H,O + 2 CO2 AH = -16.0 kcal 3. How many kcal would be released from: a. 6.00 mols of C,H12O6 reacting b. 2.13 mols of C¿HO being produced c. 20.0g grams C,H12O6 (180.1559 g/mol) reacting 4. Considering the reaction: O3 + NO → 02 + NO2, circle the impact on reaction rate of the following: a. Increasing concentration of O3: increase / decrease rate b. Decreased concentration of NO: increase / decrease rate c. Increased temperature: increase / decrease rate
