Please help with questions 1-8. Trial one is test tube number 1, trial 2 is test tube number 2, trial 3 is test tube number 3 and trial 4 is test tube number 4 and trial 5 is the standard solution. Please help with questions 1-8. Trial one is test tube number 1, trial 2 is test tube number 2, trial 3 is test tube number 3 and trial 4 is test tube number 4 and trial 5 is the standard solution. PROCESSING THE DATA 1. Write the Ke expression for the reaction in the Data and Calculation table. 2. Calculate the initial concentration of Fe", based on the dilution that resul lts KSCN solution and water to the original 0.0020 M Fe(NO solutio procedure for the volume of each substance used in Trials 1-4 This should be the same for all four test tubes. Step 2 of the 3. Calculate the initial concentration of SCN, based on its dilution by Fe(NO s)s and water. If you don't do this correctly, everything else will be WRONG! 4. Calculate [FeSCN2 leg for each of the four trials. 5. [Fe loq: Calculate the concentration of Fe" at equilibrium for Trials 1-4 6. ISCNleq: Calculate the concentration of SCN- at equilibrium for Trials 1-4 sion and the values substituted in Calculate Kc for Trials 1-4. Be sure to show the Kc expres for each of these calculations. 7. Using your four calculated Kc values, determine an average value for Kc. your Ke values? 8. How constant were tory conditions, the results you observe are expected. Meaning, even though is a "constant", it is very difficult to get a constant number using our conditions. That is ook an average. Do not be alarmed that the number is different for each trial, but do 9. In typical laborat realize the number IS, in reality, constant.Explanation / Answer
