Review: Aspirin is synthesized by the reaction of salicylic acid under the conditions shown in the balanced chemical equation below:
OH
ASO
OH
OH
Ok
salicylic acid C7H6O3
acetic anhydride C4H6O3
acetic acid C2H4O2
acetylsalicylic acid (aspirin) C9H8O4
How many grams of aspirin (acetylsalicylic acid) can be produced when 25.0 grams of salicylic acid completely reacts with 60.0 mL of acetic anhydride (density 1.06 g/mL)? Assume 100% yield.
Review: Predict the signs (positive or negative) of ΔH, ΔS, and ΔG for the exothermic reaction below when carried out at room temperature. Explain your choice for each. You should not need to refer to any data tables to answer this question.
