Question
A student performed two side-by-side reactions to test the decomposition of N2O5. The only difference between the two reactions was reactant concentration — reaction 1 started with 2 M N2O5 and reaction 2 started with 1.2 M. Which of the following statements would be true of these two reactions?
A. The rate constant k will be the same for each reaction.
B. The rate constant k will depend on the order of the reaction.
C. The rate constant k will be different for each reaction.
D. The rate constant k will depend on the concentration of reactants.
I'm guessing A

You should not have to guess: of course it is A. The rate constant is given by
k = A* e <sup>(− Ea /RT )</sup> depending on temperature
k = A* e <sup>(− Ea /RT )</sup> depending on temperature
