I ran an experiment in which three reactants produced a colored gas. I varied the initial amount of one reactant while keeping the others constant and then measured how long it took for the absorption (of a complementary wavelength) of the gas to reach .7.
My question now is how do I determine the order?
If I knew the final amount rather than the initial amount, I could plot [A]=[A]0-kt , ln[A]=ln[A]0-kt. amd 1/[A]=1/[A]0+kt and see which plot looked linear, although that would only work for integer powers. Assuming that there is a graphical approach that would work for this situation, but it eludes me. Could someone point me in the right direction? I'm assuming that I can use that fact that A is the same (i.e. the amount of gas produced when absorption=.7) for all of the reactions.
