You are given a gas phase, isothermal reaction where a → 4b at 320k. initially, you have 2 moles of a. consider a batch reactor with an initial volume of 5 l. the reaction follows an elementary rate law with a rate constant of 3 s-7. you can solve the differential equations numerically using matlab, etc. (a) plot conversion vs. time if pressure remains constant. (b) plot conversion vs. time if volume remains constant. note: plot the results from (a) and (b) on the same plot. (c) now, consider a reaction that is second order with respect to a with a rate constant of 0.4 mol-'l s-. plot conversion vs. time (1) if the pressure is constant and (2) if the volume is constant on the same plot.
