Use the concentration and rate data presented in the table below to answer the following questions about the hypothetical reaction
A + 2B + 4C ? 2D + E
Line: [A] (mol/L): [B] (mol/L): [C] (mol/L): Rate (mol/L-s):
1 0.100 0.100 0.100 3.6 x 10-2
2 0.200 0.200 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 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.
e) How do the data confirm that this is a multi-step reaction?
f) Predict the rate indicated by the "?".
g) Propose a reaction mechanism using the criteria presented in the lesson, 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"
