Question

Problem 1 The reaction A ? B is to be carried out isothermally in a continuous-flow reactor. Calculate both the CSTR and PFR reactor volumes necessary to consume 99% of A (i.e., CA = 0.01 CA0) when the entering molar flow rate is 10 mol/h, assuming the reaction rate -rA is: 1) -rA=k (k=0.05 mol/h.dm³mol 2) -rA= kCA (k=0.0001 s?¹) Problem 2 The gas-phase reaction A ? B + C is carried out isothermally in a 20-dm³ constant-volume batch reactor. Twenty moles of pure A is initially placed in the reactor. The reactor is well mixed. If the reaction is first order (-rA= kCA with k = 0.865 min?¹), calculate the time necessary to reduce the number of moles of A in the reactor to 0.1 mol.

The reaction
A ? B
is to be carried out isothermally in a continuous-flow reactor. Calculate both the CSTR and PFR reactor volumes necessary to consume 99% of A (i.e., CA = 0.01 CA0) when the entering molar flow rate is 10 mol/h, assuming the reaction rate -rA is:
1) -rA=k (k=0.05 mol/h.dm³mol
2) -rA= kCA (k=0.0001 s?¹)
Problem 2
The gas-phase reaction
A ? B + C
is carried out isothermally in a 20-dm³ constant-volume batch reactor. Twenty moles of pure A is initially placed in the reactor. The reactor is well mixed. If the reaction is first order (-rA= kCA with k = 0.865 min?¹), calculate the time necessary to reduce the number of moles of A in the reactor to 0.1 mol.
