Problem Scenario A - Model Prediction and Analysis An isothermal variable-volume batch reactor was loaded with pure A and used to carry out multiple runs of the following gas-phase reaction at a pressure of 3 bar (results in Table A1 ): 2AB Table A-1 Volume proflie for reaction runs at different temperatures and starting volumes (a) Use the available information to confirm that the reaction is elementary and determine the Arrhenius constant [(moldm3)1min1] and Activation Energy [Jmol1] for the rate constant. (b) Generate an appropriate plot to demonstrate how the concentration of B varies with time for an operating pressure ranging between 1 and 5 bar. Where. required, use initial parameters and conditions from one of the runs in Table A1. (c) Discuss the impact on the system if the feed were to include an inert contaminant. Your discussion should include a numerical example with associated theoretical links
