1. Looking at Table 5 (results file), how is Kc related to the initial concentrations ( [Fe3+]o and [SCN–]o)? Is it what you expected? (Explain briefly) (2 marks)
2. To obtain [FeSCN2+]eq in tube 5, you made the assumption that 100% of the ions SCN– had
reacted. Now that you know the value for Kc (average in table 5), build an ICE diagram to calculate the true percentage of SCN– reacted in tube 5. Comment on the validity of the assumption. (Make sure you include the ICE diagram in your answer) (3 marks)
3. Use data in table 6 (result file) to plot the graph of ln(Kc) versus 1/T. From the graph, determine the enthalpy (DH) of the reaction, show your work below. Copy and paste the graph below and include with this lab report. (2 marks for the graph, 1 for Enthalpy )
Please note, for this report you may write out the answers to question 1 and 2 by hand, scan the file and submit as a pdf. You can use the uprint printers to scan and e-mail the file.
