you arrived at each answer. (Show your method)
b) What is the overall order of the reaction?
c) Write the rate law expression.
d) Calculate the rate constant, k and provide the proper units.
e) If (C2H5)2(N2) is formed at a rate of 9.45 M/s in experiment 3, what is the rate of
appearance of HI?
f) In experiment 3, assuming it goes to completion, if all of [(C2H5)2(NH2) ] is
reacted, what would be the amount of 12 remaining?
