complex ion in on What does e of a solution to the concentration of the [Pe(phen o The biank "b" represent in the Beer-Lambert Law 3 In the experiment A ed forthe dution and Activation Energy An application of Kinetics theatiatinenergy war atacted the decomposition of the complex? a) Heat ) Light o Acid Law determine the concentration of a sohution containing [Fe(phen)) complex ion if an t of 0.851 was recorded for the solution. Use the molar absorptivity value of Base 32) Using the Beer-Lambert Law the absorbance measuremen 1.14 x 10* L/mol cm for the complex ion. 7.46 x 10 M b) 6.55 x 10* M 3 9.71 x 10 M 134 x 10 M X3) In the experiment Anhenus Equation and Activation Energy- An application of Kinetics the activation energy for Actvaton Energy the decomposition of [Fe(phen)] the natural log of the rate constant was determined by rearranging the Arrhenius equton and plotting 1/T versus 0.0032 0.00325 0.0033 0.00335 0.0034 0.00345 0 From the experimental data below, calculate the activation energy for reaction studied (Gas constant= 8.3 14 3/K-mol) a) 111.1 kJ/mol Y-13368+39.34 -2 b) 133.68 kJ/mol c) 39.5 k/mol d) 1642 kJ/mol .6 .7 on energy of this exothermic reaction can be represented by which energy diagram? Diagram A 34) Activati DiagramD Diagram B Diagram c Reaction Progress Reaction Progress Reaction Proaress Reaction Progrests a) Diagram A b) Diagram B Diagram d) Diagram D

Explanation / Answer

30) Ans = d- path length

Given that

Beer-Lambert's law is A = ebc

where  

A = absorbance

e = molar absorptivity coefficient

c = concentration

b = path length
