Question #57680
Use the concentration and rate data presented in the table below to answer the following questions about the hypothetical reaction:
A + 2B + 4C arrow 2D + E
Line [A] [B] [C] Rate (mol/L∙s)

1 0.100 0.100 0.100 3.6 x 10^-2
2 0.200 0.100 0.100 3.6 x 10^-2
3 0.100 0.200 0.100 7.2 x 10^-2
4 0.200 0.200 0.200 2.9 x 10^-1
5 0.300 0.200 0.300 ?

a) Why would you expect this reaction to be a multi-step reaction, based on the overall reaction?
b) What is the order of the reaction, with respect to each reactant?
c) What is the overall order of the reaction?
d) Write the rate law equation?
e) How does the rate law equation confirm that this is a multi-step reaction?
f) Predict the rate indicated by the "?"
g) Propose a reaction mechanism with the third step as the rate-determining step.
h) Draw a potential energy diagram to illustrate this reaction mechanism, assuming that the overall reaction is endothermic. Label reaction intermediates with "RI", and activated complexes with "AC".
