Lab Report 5

Please help me with #2b & #3 using the data.

We are stuck on 9.  We get how Q is 16 and rxn goes left.   at eq 2+ x.    2 + x.    -2 x We get x= 1.    Therefore  k = 4.  Please help us.   Questin 9.  See conditions from 8 This is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months. We do questions at the back of the textbook by Zumdahl and Zumdahl

help please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working

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? Experimental data: Carbon type: F-400 Carbon size: 200 × 400 .

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.

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. Naphthalene-2,3- dicarboxyaldehyde Cyanide OH Fluorescent product HN. Fluorescence intensity Concentration (uM) of added carnosine in final 100 µL 0.0 0.465 1.0 0.698 2.5 1.029 5.0 1.651

Only 100% sure experts solve it correct complete solutions need to get full marks it's my quiz okkkk.take your time but solve full accurate okkk chemistry expert solve it

Q4. Your report must include clearly labelled plots you have used to make the determination of the reaction order.       Compare R2 values

Explain how changing Experimental Volume impacted the kinetics of the reaction. Compare to your prediction. Be concise. ( in short sentence)

I need the answer for this question as Sage Math Code. It's a linear algebra

Based on your ICE table (Part 2) and the definition of Ka, set up the expression for Ka in order to determine the unknown. Each reaction participant must be represented by one tile. Do not combine terms.
