4. A student carefully weighs out exactly 2.000 grams of salicylic acid for the synthesis of
aspirin experiment but spills about half the acetic anhydride. He decides to go ahead with the
experiment as his laboratory Instructor explained acetic anhydride was "in excess”. How
might this affect his results? Would his theoretical yield calculation still be accurate? Explain.

How does concentration affect reaction rate

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
