1. You made wintergreen in Lab 1 by reacting salicylic acid (C 7H,O3) with methanol (CH3OH). If you react salicylic acid with acetic acid (C2H402). you can make aspirin The rate law for this reaction is: rate k [C H6o3 IC2H421 The salicylic acid and acetic acid reaction is slow. Sulfuric acid, H2SO4, is used as a catalyst in this reaction. The rate law for this reaction with the H2SO4 catalyst is: rate k [C 2H,02l [H2SO, a. If the...

QUESTION 3 Salicylic acid reacts with acetic anhydride to form aspirin and acetic acid as shown. Use the equation to answer Questions 3 – 6. (salicylic acid) (aspirin) C7H6O3 (s) + C4H6O3 (l) → C9H8O4 (s) + CH3COOH (l) MM = 138 MM = 180 If we divide 180 by 138 we find that 1.00 g salicylic acid will produce a maximum of 1.30 g aspirin. 3. A student starts with 3.20 g salicylic acid. What is the maximum amount...

QUESTIONS 1. What is the purpose of the sulfuric acid (yes, it's a catalyst, but why is it a catalyst? What is it doing that makes the reaction possible? Would the reaction just go slower without it, or would the reaction not go at all? Why?) 2. If isobutyl alcohol (2 methyl propanol) is used instead of tert butyl alcohol, a mixture of products is obtained. One the products is the same as the product obtained with the tert butyl...
