[CHM 112] Quiz Preparation

[Andrew J. Pounds]

Yes.  Since I told you that it is a first order reaction the rate law is 
of the form:

rate = k [conc]

Just divide the rate by the concentration in this case to get the k 
values.  Once you get a rate constant for both temperatures,  use them 
in the second part of the quiz to come up with Ea.  Once you get Ea, use 
the Arrhenius equation to come up with the frequency factor (A).   With 
a complete Arrhenius expression you should be set to come up with a rate 
constant at any temperature, and subsequently be able to tell me the 
rate at that temperature given the initial concentration.
