In the production of m-xylene (CSH10) from mesitylene (CəH12) over a catalyst, some of the xylene reacts to form toluene (C,Hs): C3H12 + H2 → C3H10 + CH4 C3H10 + H2 → C,H3 + CH, The second reaction is undesirable because m-xylene sells for $0.65/lb whereas toluene sells for $0.22/lb. The CH, is recycled in the plant. One pound of catalyst is degraded per 500 lb of C;Hs produced, and the spent catalyst has to be disposed of in a landfill that handles low-level toxic waste at a cost of $25/lb. if the overall selectivity of CsH10 to C,Hs is changed from 0.7 mole of xylene produced/mole of toluene produced to 0.8 by changing the residence time in the reactor, what is the gain or loss in the $/100 lb of mesitylene reacted.
