5.) The following mechanism has been proposed for the reaction from Question 4. CgH;COOH = CgH;CO2H† (fast; constants k,and k-1) CgH;CO2H = CgH;CO+ + H2O (fast, constants k2and k_2) C&H;CO* + HX + H20 → C¿H&NH2 + N2 + CO2 (slow; constant k3) A. What intermediate(s) are formed in this mechanism? B. What is the rate law, based on the above mechanism? C. The overall rate constant for this reaction is 0.200 x 10* L mol' s'. Is this value consistent with your answer to B? Explain. D. Sketch a reaction-energy diagram consistent with the above mechanism and the enthalpy change calculated earlier. Label the enthalpy change and each transition state. Explain the appearance of your graph.

Question

The overall reaction #5 is referencing is above (first image). I DO NOT need help with #4, just #5, but 5D has to do with 4.

I'm looking for some help with my main part of my question, number 5 A-D, but part 5D also asks for enthalpy values (I guess calculated from my first image)? I think the reaction is second order, but I'm not sure - I think it's second order because of the units Lmol^-1s^-1? And I don't really understand how to sketch a reaction energy diagram... 

4.) HX is used as a reagent in the reaction below. ÑH2 + NEN OH + HX A. What functional-group transformation occurs in this reaction? B. What is the likely identity of HX? Verify your decision with the table of Ka values in the back of your textbook. Consider the following thermodynamic data for the reaction shown above. HO. + HX + NEN + AH': (kJ/mol) -386 260.1 30.00 -393.5 S° (J/mol K) 166 146.0 191.3 191.5 213.8
