Question

CHM 1046 Workbook Florida International University 1) The isomerization reaction shown below follows first order kinetics at 500 K CH,NC (g) CH CN (g) a) Use the rate constant you determined in example 3 on page 4 to determine the half life of this reaction. o53 t Va- 657メ10 b) Use the half life you just determined to predit how long it will take for the concentration of CH3NC to reach 25% of its original value? Compare the answer you got here to the one you got in example 3 and discuss whether the two answers are in agreement. Explain why the answers are/are not in agreement. Compare the two methods and determine under what circumstances you can use which method.
