For an elementary, gas-phase reaction 2A+B+ 4C, the rate constant is k for the reaction rate of A. The reaction is taken place in a flow reactor. The concentrations entering the reactor are Cao = 1 mol/dm, CBo = 1 mol/dmand Cco = 0 mol/dm? Which of the following statements is correct? Answer: (A) A = KCCB (B) YAO = 1 (C) 8= -1 (D) E = y28 (E) ng = 2r = Consider a liquid-phase reaction A + 2B in a CSTR. The initial concentration of A is 10 mole/dm3 entering the reactor. If no B is entering the reactor and the conversion of A is 80%, what is the concentration of B exiting the reactor? Answer: (A) 2 mole/dm; (B) 8 mole/dm; (C) 10 mole/dm; (D) 16 mole/dm"; (E) None of above
