what evidence do you have that TPGS-750M increases the reaction rate? How does TPGS-750M act to increase the reaction rate? **green chemistry
what do you think will happen to the rate of reaction if one increases the concentration of substrate to 6ml? why does the speed of reaction level off?
2. You are told in the introduction that water increases the rate of the Diels-Alder reaction relative to rates observed in conventional organic solvents. One explanation for this is the hydrophobic effect. What is the hydrophobic effect? How does it increase the rate of a Diels-Alder reaction?
Suppose you have a following reaction: How does the reaction rate change increase, decrease, does not change) if you: a) increase the concentration of sodium iodide twice b) use n-hexane as a solvent instead of acetone c) use 2-bromopropane as electrophile instead of bromoethane d) use two times higher volume of solvent (keeping the amount of both alkyl bromide and sodium iodide the same). In each case use one-two sentences to justify your answers CH3CH3Br + Nal acetone → CH2CH3...
How does population size affect the rate of evolution? Describe any evidence you might have from experiments to back up your claim.
What does evidence based practice mean to you? Do you think it is important? Why or Why not? Do you have any experience with research or evidence based practice? Why do you think this course is required in this program? What do you hope to learn through participating in this course?
In enzymes, what happens to the rate of reaction as the temperature increases? Explain in terms of how molecules collide and product conversion rates. What happens to the enzyme activity if you infinitely increase the temperature?
Can you answer this questions in details? Please explain and write the answer for each questions Post-lab questions 1) What evidence would appear in the 'H-NMR and IR spectra indicating over-oxidization of the aldehyde? 2) Show how compound A could be synthesized from 4-bromobenzaldehyde using a combination of reactions that you have studied in CHEM 342 and looking ahead to section 23.5 of your textbook (Klein). Clearly draw and name the reactions you propose (you do not need to show...
Increasing the temperature of a reaction increases the rate of of reaction, why? Does it change the free energy of the transition state?
1. What effect does consentration have on the reaction rate? 2. what would you predict for the rate if 2.5 ml of water were mixed with 2.5 ml of the potassium iodate solution then 2 ml of the sodium meta-bisulfite/starch solution were added? pleas explain how you arrived at your nswear?
