For the reaction A → (k₁) B → (k₂) C with k₁ = 0.25 hr^-1 and k₂ = 0.3 hr^-1. The initial concentration of both B and C is 0.25lbmol/ft³ while A is1lbmol/ft³.What is the concentration of B in lbmol/ft³ after 1 hour in the batch reactor?

The liquid-phase bromination (B) of 2,4,6-trimethylacetophenone (A) is: A + B → C + D with a rate of -r_A = 0.0434C_AC_B in M/s. A battery of three identical CSTR’s with equal volumes in series will be used. The volumetric flow rate of the feed is 1 L/s while the initial concentration of feed A is 0.05 M and B is 0.06 M. The required conversion is 80%.

What is the overall conversion of the first CSTR?
