Assignment 2: Analyzing Reaction Rate Data

 

Due Time and Date: Wednesday, Oct. 14th, 3:30 PM

 

  1. The isomerization reaction

    2. was carried out in an isothermal batch reactor and the following concentration-time data were obtained:

    t (min) 0 5 8 10 12 15 17.5 20

    CA (mol/l) 4.00 2.25 1.45 1.00 0.65 0.25 0.06 0.008

    Determine the order of the reaction and the specific reaction rate constant. Note: you may want to examine this data closely.

     

  2. Consider the gas phase constant volume decomposition of dimethyl ether at 504oC in a batch reactor:

Assuming that only dimethyl ether is initially present, determine the specific reaction rate constant k from the data below. Hint: first check to see what the fractional conversion of dimethyl ether is at the end of the reaction and make your judgements accordingly.
