Chemistry Questions Worksheet

Question 1 (10 points) – Use this data in this spreadsheet to make the appropriate graphs to determine the activation barrier and the pre-exponential factor (A) for the reaction. Make sure to show the equations and R2 values for any trendlines on the graph and label all axes with units. If you have to do any calculations in Excel, make a cell in the spreadsheet where you show your calculation function. Show any necessary calculations for the activation barrier and the pre-exponential factor on a handwritten sheet of paper which will be scanned as a PDF. Question 2 (15 points) – Consider the following reaction:2 AB —> A2 + B2Use the data in the spreadsheet and make any appropriate graphs to determine the order of the reaction with respect to [AB]. Make sure to show the equations and R2 values for any trendlines on the graph and label all axes with units. If you have to do any calculations in Excel, make a cell in the spreadsheet where you show your calculation function. Determine the rate constant of the reaction at this temperature. Write the rate law for this reaction from this data. Explain the following: Is this reaction a one step or multi-step mechanism? How do you know? Explain in 1-2 sentences. Show any necessary calculations, write the rate law, and write your explanation handwritten sheet on a sheet of paper which will be scanned as a PDF for your submission.
