The hydrocarbon propene (CH3-CH=CH₂) can react in two different ways with bromine (Chapters 12 and 14). Br Br T (i) CH3-CH=CH, + Br2 → CH3CH—CH, (ii) CH3-CH=CH₂ + Br₂CH₂-CH=CH₂ + HBr − Br -1 (a) Using the bond strengths (kcal mol¹) given in the table, calculate AH° for each of these reactions. (b) AS ≈ 0 cal Kmol for one of these reactions and -35 cal K-¹ mol-¹ for the other. Which reaction has which AS°? Briefly explain your answer. (c) Calculate AG for each reaction at 25°C and at 600°C. Are both of these reactions thermodynamically fa- vorable at 25°C? At 600°C? (a)tubong son Jouborg
