Hi! You are going to need to use the Arrhenius equation ( k = A e^{\frac{-E_{a}}{RT}} ) to determine k for the original pathway, then for the catalyzed pathway. k will be exponentially higher for the catalyzed pathway due to the change in activation energy, so expect a large ratio as you will be fi...

Re: Sapling Week 5/6 #9 Oxidation Number
Hi! I can definitely explain. So quantum numbers have some basic rules you have to know. The oxidation numbers in a neutral compound should add up to zero. For the example where there is a -1 charge, it should add up to that number. Oxygen normally has a O# of -2 (thats just a rule). Then you multi...

You would figure the second question out by asking yourself which of the three Lewis Structures of the carbamate ion is the least stable. To do this, you would look at the formal charges of the three structures and whichever one is more charged (as in it has more atoms with negative/positive formal...

I am confused on the second part to the question..
"Which of the Lewis structures would be expected to contribute the least to the overall structure of the carbamate ion?"
How would you figure out this question?
Thank you!!

Re: Rydberg Equation
I'm not sure but I thought that n1 refers to the final level that the electron returns to, while n2 is the initial level. I don't necessarily think that you would always subtract the higher level from the lower one; if the electron absorbs energy and is excited to a higher level, n1 would be higher...

Re: Sapling HW #7
In addition to what everyone else said, make sure that you convert your wavelength from m to angstroms. (1 angstrom=10^-10m). To do this, you take your wavelength in meters / conversion factor (10^-10).
