1) Given this data in a study on how the rate of a reaction was affected by the concentration of the reactants


Initial Rate,
RUN # (A), M (B), M (C), M mol L-1 s-1
1 0.200 0.100 0.600 5.00
2 0.200 0.400 0.400 80.0
3 0.600 0.100 0.200 15.0
4 0.200 0.100 0.200 5.00
5 0.200 0.200 0.400 20.0

The rate constant for this reaction (all in the same units) is?

I am not sure where to start since there are so many numbers given.

You start by finding a set of two reactions in which A changes concn but B and C do not. Compare the concn changes and rate changes to find the order with respect to A. Do the same with B and C.
