Determination of order of reaction from ln() graphs

  1. May 14, 2014 #1
    I have to say if each reactant is first, second or zeroth order.

    Now, I know that usually, we have plots of ln([]) over time. But my teacher wants to trick me.

    Here is how I do this:
    Take two data points: convert them to [ ] and normal rate (remove the ln() function).
    Compare the two data points to see influence of [].

    Is there a faster way?

    When you plot like that, what does the slope of these figures say about the reaction rate?
    What does a figure of y=A^t look like, what does y=ln(A^t) look like?

    oh yes, and note that there is a direct relationship between time and concentration, which is known from the exact solution over time for the concentration when the reaction order is 0,1, or 2.
