Hi Dr. Bob would you please tell me what D rpresents?

Thank you!
What is the reactant, products, and what compounds is it? Is it H2O, O2, or what? What are the transition molecules? Help please.
Do as below to get to the image. I couldn't put the URL in and it isn't my website. I just found the picture that i need there. Do i48, dot, tinypic, dot, com , forward slash, 14w59oi, dot, jpg.

I hope you'll be able to find it.
Thank you for helping me.

I couldn't find it.

I don't think that i'll be allowed to submit someone elses URL. i48.tinypic (put the com here) /14w59oi.jpg. Try this. I don't know why it isn't coming up for you. It works fine when i open it.

I found it this time but I don't know the color scheme. I suspect one molecule may be CH3X which makes the other H-something. If you know the color scheme I may be able to help; otherwise, I can't.

If you mean the color of the line it starts as very dark red or burgandy(don't know if it is spelled rihgt) then a red color all the way.

No, I mean the color of the atoms. I think the white spheres are H and the black probably C. Green is often a halogen. Red is sometimes oxygen.

Yes the white spheres are H and black are the C. I don't see green, but i see blue.The blue is nitrogen and the red is oxygen. If it is green then it is either Fluorine or Chlorine.

These don't hold up for valences but
A = reactants = HO + CH3N
B = the intermediate = HO-CH2N
C = product = HO-CH3 + N

What does D represent?

1 answer

D represents the time it takes for the reactants to obtain enough energy to reach the peak of the activation energy needed to form the intermediate complex of B.
