Answer 1

Answer #1

First,

Plot Ca vs. t (zero order)

Plot ln(Ca) vs. t (firstorder)

Plot 1/Ca vs. t (second order)

In(C)1/C 18.3 2.906901 0.054645 12.2 2.501436 0.081967 8 2.0794420.125 5.51.704748 0.18181810 3.5 1.252763 0.285714 1.7 0.530

For the best fit, choose the STRAIGHT line

The best fit is 1st oder

therefore

-Ra = k*Ca^1

n = 1

units of K must be then 1/s or s^-1
