Question

I. The following mechanism has been proposed for the formation of N2 and H2O from H2 and nitrogen monoxide.

Step 1              2 NO                    N2O2     (fast, equilibrium) This is reversible

Step 2              N2O2   +   H2                        N2O   +   H2O      (slow, RDS) This is not reversible

Step 3              N2O   +   H2                       N2   +   H2O     (fast) This is reversible

 a.  What is the overall reaction for this mechanism?  

 b.  What are the intermediates if any are present?  

c.  Write a rate law for each step of the mechanism and list the molecularity of each step.  Be sure to include any reversible steps as well.  

d.  What is the predicted rate law for this reaction?  Be sure to show all your work to receive credit. 

e.  What are the expected units for k if time was in units of seconds.  

 

 

II.The following reaction has a rate constant of 0.760s-1 at 1000. K and a rate constant of 0.870s-1 at 1030. K.  What is the activation energy for this reaction?
