Nitrosyl chloride (NOCl) decomposes in a second order reaction. At 425°C, the rate constant is {k} x 10–4 M–1min–1. If the initial concentration of NOCl is {M0} M, what will be the concentration after {t} minutes? For full credit Report your answer rounded to two decimal places.  Ex:  3.210 = 3.21 Include the correct unit.  

BONUS Calculate the activation energy (in kJ) for a given reaction using the data in the chart below.  The rate constants were measured at two different temperatures in K.   Trial Rate constant Temperature (K) 1 {k1} x 10–4 {T1} 2 {k2} x 10–2 {T2} For full credit Report your answer rounded to one decimal place.  Ex:  43.21 = 43.2 Include the correct unit. Additional information you may or may not need: R = 8.314 J/(K*mol)

What is E°cell for the reaction below? Do not use the REAL values for these species Sn 4+ (aq) + 2 K (s)  ⇌  Sn 2+ (aq) + 2 K + (aq) For full credit Report your answer with 4 significant figures. Include the correct unit. Additional Information you may need for this problem: Assume standard conditions Do not use the REAL values for these species; instead use these: Sn 4+ (aq)  ⇌  Sn 2+ (aq)   Ered = {Sn} V 2 K (s)  ⇌  2 K + (aq)  Ered = – {K} V

A certain second order reaction has a rate of {r1} M/s when the concentration of reactant A is 0.25 M. What is the rate for this reaction of the concentration of A is 1.5 M? Format your answer: Enter your answer to two decimal places. Include the correct unit

Above, we show several lines of Names.txt, but in practice, the file may be much longer. All names in the output file should be uppercase. Make sure you read from input and output files as specified on the command line. Complete this program, Exam 2 Part 2: Question 3, on CodeBuddy. Here is an example of the correct output for the file above (again, any case—upper, lower, or mixed—is correct): alpha_names.txtDAVID OMAN MCKAYELIZA ROXCY SNOWEMMA HALE SMITHJOSEPH FIELDING SMITHJOSEPH FIELDING SMITHJOSEPH SMITHLINDA KJAR BURTON We will execute your code with the following command (or something similar): python studentcode.py Names.txt alpha_names.txt  As always, make sure to use system arguments to get the file names or your program will fail.
