for the reaction: acetaminophen + (NaOH/EtOH note: etoh is ethanol) and butyl iodide ---------------> 4-butoxyacetanilide a) The first step in this reaction is to reflux acetaminophen in a NaOH/EtOH solution, followed by the addition of butyl iodide. What is the purpose of using the NaOH/EtOH solution? Would the SN2 reaction still occur if the first step was not completed? Why or why not? b) Upon completion of the reaction (before filtration), an additional 4.0 mL of 1.0 M NaOH/EtOH was...

a Review | Constants Periodic Table Part A The Arrhenius equation shows the relationship between the rate constant k and the temperature T in kelvins and is typically written as k= Ae-E/RT where R is the gas constant (8.314 J/mol K). A is a constant called the frequency factor, and E is the activation energy for the reaction. The activation energy of a certain reaction is 47.9 kJ/mol. At 25 °C, the rate constant is 0.0190s . At what temperature...

+ The Arrhenius Equation: Graphical Method 9 of 11 Review Constants Periodic Table There are several factors that affect the rate constant of a reaction. These factors include temperature, activation energy steric factors (orientation), and also collision frequency, which changes with concentration and phase All the factors that affect the rate constant can be summarized in an equation called the Arthenius equation Part A k=A-E/RT where k is the rate constant. A is the frequency factor, Eis the activation energy...
