Please upload your full solution to the following problem. For the experimental isotherm data given below, determine the Freundlich and Langmuir isotherm parameters. Apply linear regression to determine the isotherm parameters. A spreadsheet can be used for this purpose. Which of the two isotherms better describes the data?

Experiment 16-Pre-Lab Assignment Name: 1. Design a preliminary procedure including sample calculations to determine the heat of neutralization for the reaction between 1.0 M HCl and 1.0 M NAOH in kJ/mol. Use your knowledge of the chemicals, their properties, and the laboratory techniques learned thus far in this course. Any chemicals and equipment that you require will be provided in the lab. This procedure must be approved by your instructor before you can begin experimentation. unpe 16-3

You continue with the Arrhenius Plot with the slope of the curve to be approximately -12,500 K and the Arrhenius factor of 4.367 E10 hours^-1. What is the shelf life of the drug at 22 C? What is the shelf life at 4 C? Did your coworker achieve a century shelf life in either storage condition? Be sure to show your calculations.

V. Error Analysis/Questions For the following questions explain what specific error in calculating your Ksp value would occur (i.e. would the Ksp be too HIGH or too LOW), compared to the situation in which no errors occur. When you answer the question, consider how the situation affects the calculation of Ksp. Each answer must have an explanation and type the answer, please. A. The buret was not conditioned (it still had water in it) when you add the HCl. Would the Ksp be too HIGH or too LOW? B. There was Ca(OH)2 solid (that was not filtered off) in your solution to be titrated. Would the Ksp be too HIGH or too LOW? C. You measured 24.00 mL of Ca(OH)2 solution instead of 25.00 mL. Would the Ksp be too HIGH or too LOW? D. The HCl concentration was actually lower than the reported molarity on the bottle. Would the Ksp be too HIGH or too LOW?

Question attached as photo.  This is not a exam/ test question:) you can see that our prof has written sth on this question, it is a question that he wants us to practice on our own in lecture. Thanks Topic related to 1st order/ 2nd order kinetics, need excel/graph to do this question, need TWO plots to check whether they are 1st/2nd order concentration = activity * m (concentration is proportional to activity plus a constant m) 1/[A] =1/[A]0 + Kt 1/[Activity* m] = 1/[Activity0 *m] +Kt 1/[Activity] =1/ [Activity]0 + mKt Do we follow the equations of zeroth, 1st, 2nd order reactions?  What is the key idea to determine whether this data gives 1st or 2nd order kinetics? Our prof was saying that if it's linear graph, means it is in correct order. BUT i have plotted 3 datas, two of them looks kinda linear to me. (the 2nd order and zeroth order graph are similar) If we are choosing from zeroth/2nd order, how do we determine its order if it's line is similar in linearity?

1. This question is adapted from Harris 19-D. Carnosine is a dipeptide whose antioxidant properties protect cells from free radicals. Carnosine was determined by derivatization with naphthalene-2,3-dicarboxyaldehyde and cyanide followed by fluorescence detection using excitation at 445 nm and emission at 490. Quantification was by standard addition. To four aliquots of 20-ul cell lysate were added volumes of 100µM carnosine standard to generate final concentrations of 0, 1.0, 2.5, and 5.0 µM added carnosine. Solutions were diluted to 70µl before addition of 15µl of 5 mM naphthalene-2,3-dicarboxyaldehyde and 15µl of 10 mM NaCN. H H2N. OH Carnosine HN.
