Q9. (4 Marks) For the chemical reaction AC+D, Calculate the time required to consume 80% of species A in a constant-volume batch reactor, knowing that rA=K,CA,k= 5l/s and the initial concentarction of A is 200mol/mindm3 CA=VNA Q7. (3 Marks) Consider the chemical Reaction A B , The space time required to achieve 80% conversion in a CSTR is 5h. The entering volumetric flow rate and concentration of reactant A are 1dm3/min and 2.5mol/dm3, respectively. determine the value of the reaction rate, rA T=v0v Consider the reaction Calculate the time required to consume 95% of A in 1000dm3 constant volume Batch Reactor with AB CAO=0.5mol/dm3 if the rate of reaction is rA=kCA2, and k=4dm3/mol.hr The Chemical reaction Is carried out in a PFR, 80% of A and 80% of B is consumed during the reaction, the exiting concentration of A is =0.5mol/dm3 and that the concentration of B is always double the concentration of A. The rate of reaction is raA=KCAC8 and k=4dm3/molhothr and wolumetric flow rate =1000dm3hr V0=1000din4/ for Q9. Calculate the initial concentration of A(2 marks 2 ) C=2CA reachout100%.predintCA=0,5mel/dm3 CAO=0.2CA1ko=0.x0.51=2.5 pole / dm? Q10. Calculate the volume of the reactor. (3 Marks) 1.5 The The reaction A+BC was carried out isothermally in PBR with a volumetric flow rate of 500m3/s and achieved a conversion of 70%, if the concentration of B is 200mol/m3, then the FB : a) 60mol/m3 b) 140mol/m3 c) 70,000mol/m3 d) 30,000mol/m3
