Question 6 3 pts U Which equation indicates the presence of a catalyst in the reaction?...
Question 6 4 pts Calculate the TON and TOF for the reaction of benzylamine to benzonitrile if 0.5 mol% catalyst is used at 95 degrees C for 19 hours to generate an 83% yield of product. CN NH, 0.5 mol % catalyst 95 °C. 19 h Hint: 0.5 mol % catalyst means that 0.005 mole catalyst are used for every mole of reactant. You will need to use the definitions of TON and TOF to answer this question.
