HOUR EXAM#1 NAME: SS: 1. The gas-phase reaction A->B+2C takes place in an isothermal batch reactor. Originally, there is pure A in the reactor. The reaction rate law is: r=kC A 2 , k=0.03dm 3 /mol*hr. The reactor volume V=1000dm 3 (constant), the initial pressure P 0 =10 5 Pa, and the temperature T=400K. What is the pressure in the reactor after 10 hours of operation?

2. Two CSTR reactors (of the same volume) and a PFR reactor are connected in series. A reaction: A->B takes place in these reactors with a reaction rate law of r=kC A (k=1.0 hr -1 ) . The inlet concentration in the first CSTR is C A0 =3 mole/dm 3 , the inlet molar flow rate of A is F A0 =7000mol/hr, the volume of each CSTR is

Unformatted text preview: V CSTR =1000 dm 3 , and the volume of the PFR is V PFR =300 dm 3 .. What is the conversion X at the exit of the PFR? 3. Consider the reaction A->B. The reaction rate law is r=KC A /(1+LC A ). Compare the volumes of a single CSTR or a single PFR needed to achieve 80% conversion for the same inlet molar flow rate. 4. Consider a gas-phase reaction: A->B+C taking place in a CSTR reactor. The reaction rate law is r A =kC A (k=1.0hr-1 ), the inlet concentration is C A0 =3 mole/dm 3 , the inlet molar flow rate is F A0 =5000 mole/hr, and the reactor volume is V CSTR =1000 dm 3 . What is the conversion X?...
