Part 1:- 1) rate = ∆S / ∆t = k [S 2 O 3 2- ] m ln ∆S / ∆t = ln k [S 2 O 3 2- ] m ln ∆S – ln ∆t = ln k + ln [S 2 O 3 2- ] m ln ∆S – ln ∆t = ln k + m x ln [S 2 O 3 2- ] – ln ∆t = m x ln [S 2 O 3 2- ] + ln k – ln – ln ∆t = m x ln [S 2 O 3 2- ] + (ln k / ln ∆S) y = mx + b y = -ln ∆t, x = ln [S 2 O 3 2- ] , b = (ln k / ln ∆S) 2) By using the regression feature in SigmaPlot, the order of the reaction is 1.0179. However, since the order needs to be an integer, this is rounded to 1. Therefore, the reaction is 1 st order with respect to [S 2 O 3 2- ]. Part 2:- 3) The slope of the line is 4654. 4) – ln ∆t = ln A – E a / R (1/T) slope = - E a / R E
