Homework Statement I am given a linear graph that is Absorbance vs. Concentration. How do I find epsilon in the beer's law equation? Homework Equations Beer's law: A = Epsilon x L x c The Attempt at a Solution I just need a general explanation. Thanks.

Thanks you! I got the equation to be y = -69.315x + 7.7832 without plotting the last point. This means the rate constant is -69.3 respect to [O]. It is negative because the concentration is going down as time increases. Is that correct?

Homework Statement The rate of the reaction was studied at a certain temperature. O(g) + NO2(g) --> NO(g) + O2(g) In the first set of experiments, NO2 was in large excess, at a concentration of 1.0 * 10^ 13 molecules/cm3 with the following data collected. time (s) [O] (atoms/cm3) 0...
