Transcribed Image Text:2. Reactant A decomposes by three simultaneous reactions to form three products, one that is desired B and two that are
undesired X and Y. These gas phase reactions, along with the appropriate rate laws, are listed as follows:

The reactions are carried out in a CSTR. CA0= 0.4 mol/dm', vo= 2 dm/s. The selectivity of B over X and Y is defined SBXY=
. Determine (i) C, at which maximum selectivity can be obtained. (ii) the maximum selectivity SB/XY, (iii) The
Ix +ry
reactor volume of the CSTR, (iv) the conversion X at the maximum selectivity, (v) concentration of Y, Cy=? (
