I (your name here) pledge that this assignment has been completed in accordance with the George Mason University Honor Policy as well as the policy set by the course. This work is my own and bears no resemblance to any other student’s work (past or present).
Purpose Reference Materials and Chemicals Reaction: Procedure Results: Raw Downloaded Data Calculated Data for each temperature: oles of HCl moles of borax concentration of borax – using both equations (A and B! ) Sample calculations – calculations of your data alone for all of the items listed above? Graph lnK vs 1/T Show a trendline and provide the R2 value Determine? H (kJ/mol) and? S (J/mol K) from the graph SHOW HOW YOU DO THIS!! Printing Tables? Large tables should be printed in the landscape mode and sometimes it might be necessary to go to “page setup” and select “Fit 1 page” to make the page fit on one page. ? Include column and row headings on the printout so that the instructor can more easily understand equations used.

This can be done by going to File > Page Setup > Sheet tab > Select “Row and Column Headings”. Discussion: In your discussion section address the following questions:? Why is it unnecessary to precisely measure the amount of solid borax used? (This answer should be greater than 3 sentences in length! )? Should Ksp vary with temperature? Does it? Why or why not? Does the graph of ln (Ksp) v. 1/T have any deviating values? If so why? What could be the sources for these errors? Discuss the logic behind the determination of?
