TAUk2k1Rk3Sdk4k5M Write down the following rates; rA= rh= rss= rTm ru= rM= (b) B is desired product for following parallel reaction ABrs=1+2CA2CAmol/its ACrC=1.2CA Initial concentration of A is 4M. The conversion of A at the outlet is 0.99(xat=0.99). (i) What is the selectivity of B to A(saA). (ii) What type of reactor(s) should be used in order to maximize the production of B? (iii)What are the concentrations of all (A,B,C) components at the outlet of the reactor(s) recommended in part (ii)
