A mixture of 75% m-xylene and 25% inerts is fed into a tubular reaction at a volumetric flow rate of2m;/min and a total concentration of 50 mol/m:. Metal-xylene is reacted over a zeolite catalyst and thefollowing parallel reactions were found to occur:m-Xylene k1→benzene+methane,k1=0.2 s-1at 673.0m-Xylenek2- p-xylene k2=0.7 s-1 at 673oCa. Calculate the space time to achieve 95% conversion of m-Xylene for these elementary gas-phasesreactions.b. How would your answers change if you need to consider the reversible reaction and isomerization toform o-Xylene?
