Aspirin, C₉H₈O₄, Slowly Decomposes at Room Temperature by Reacting with Water

question 43

Essay

Aspirin, C₉H₈O₄, slowly decomposes at room temperature by reacting with water in the atmosphere to produce acetic acid, HC₂H₃O₂, and 2-hydroxybenzoic acid, C₇H₆O₃ (this is why old bottles of aspirin often smell like vinegar):
C₉H₈O₄ + H₂O  HC₂H₃O₂ + C₇H₆O₃

Concentration and rate data for this reaction are given below. Write the rate law for this reaction and calculate k (be sure to include the correct units).
