Reasoning 1 10 00 Ml Of 0 10 M Naoh Is Reacted With 10 00 Ml Of 2 5x105 M Mb The Absorbance A Of The Reaction Mixture 2 (35.9 KiB) Viewed 9 times
reasoning 1. 10.00 mL of 0.10 M NaOH is reacted with 10.00 mL of 2.5x105 M MB. The absorbance A of the reaction mixture at 590.2 nm vs time is measured. A plot of In(A) vs. t, gives a straight line with a slope = -0.0025 s¹. What can you conclude about x the order with respect to MB? (explain your reasoning for full credit) X= Explain Why? 2. The experiment is repeated with 10.00 mL of 1.0 M NaOH mixed with 10.00 mL of 2.5x10-5 M MB. This time the slope is -0.0250 s¹. Using this data and the data from question 1 determine y. (show all working) Show calculations here:
3. Calculate k for this reaction using the data from question 1. Pay attention to the units of k as well as the significant figures. 4. What is the overall reaction order (2 marks - show reasoning for full credit) 5. Extra Credit: Could this reaction theoretically occur in one step from what you have learned about the rate law? (2 marks- explain your reasoning for credit)
