Question

1. Graphical Analysis (6 p). Using only the D2L EXCEL data for the UNKNOWN you are assigned to perform a graphical analysis. Paste-in all the graphs for a complete analysis. Include the locax equation of the line and the R2 value for each.

Answer 1

i order reaction For [0), = [cl. - kt ...() where, c = Initial concentration of reactant (c) = Concentration of reactant at time karate contant ť a time. Now, from Lambert - Beer's law we get, A = Exlx where, A- Absorb ance &= Molar absorptivity at particular wavelength ea bath length of photo call Carolar concentration At a particular wave length An constant & l ase constant. do, Axc . & CAJ – atel at

dr The rate law of the hot order reaction - d = k where kan contant, - atlak here, Abs vle time giver estraight line whore equation like a sorder integrated rat & law eanation y = -0.00160 + 0.9189 ... fü) Now, compairing ernation(i) 4 (i) weget, [el= y, tax, (C. = 0.9189 slope ark = -0.0016 : K = 0.0016 M hr-1 : order of reaction for) = 0 rake contant (K) = 0.0016 m.hr at 24°c (3) To answer this activation energy Ea) & rate constant vare needed at different tenperature.
