A reaction is to be carried out isothermally in a continuous flow reactor. The entering volumetric flow rate = 10 dm^3/hour. The feed molar flow rate FAO = 6 mol/hour. (a) -rA = k (b)-rA = k*CA (c)-rA = k*CA² AB with k = 0.040 mol/(hr* dm^3) with k = 0.00012 sec¹ with k = 320 dm^3/(mol*hr) Use the reaction information and k-values from Problem Three, parts (a) through (c), to calculate the time required to consume 96% of species A in a 1200 dm^3 constant volume batch reactor with a CÃO = 0.6 mol/dm^3

A reaction AB is to be carried out isothermally in a continuous flow reactor. The entering volumetric flow rate v = 10 dm^3/hour. The feed molar flow rate FAO = 6 mol/hour. (a) -rA = k (b)-ra= k*CA (c)-rA = k*CA² with k = 0.040 mol/(hr* dm^3) with k = 0.00012 sec¹ with k = 320 dm^3/(mol*hr) Use the reaction information and k-values from Problem Three, parts (a) through (c), to calculate the time required to consume 96% of species A in a 1200 dm^3 constant volume batch reactor with a CAO = 0.6 mol/dm^3

Follow-up Question

can you plz help with this followup question 

Bonus Problem Q: List all of the possible forms of energy occurring while this reactor is operating (essentially all non- zero terms that would go into an energy balance). You should probably sketch a diagram of the reactor to find all of these forms of energy This reactor also operates at a temperature of 600 K and is equipped with a cooling jacket that receives a liquid cooling fluid at 288 K. The reaction is in the gas phase and has a AH o = -15,000 J/mol. Assume that no phase changes occur in the reactor or in the cooling jacket. Also, assume that the inlet and the outlet streams have no elevation changes and their flow rates are maintained at all times. T = 600K ΔΗ = -15,000. Note: ● ● J mol ● No phase changes occur in the reactor or in the cooling jacket. No elevation changes, flow rates are maintained at all time. Gas phase reaction Receives cooling liquid at 288K.

operating conditions are what you just solved for: 

CAO=0.6

V=1200dm3

 

plz help me find energy forms 

Consider the PFR from Problem 3 operating under the conditions of Part (b). This reactor also operates at a temperature of 600 K and is equipped with a cooling jacket that receives a liquid cooling fluid at 28 K. The reaction is in the gas phase and has a AH° = -15,000 J/mol. Assume that no phase changes occur in the reactor or in the cooling jacket. Also, assume that the inlet and the outlet streams have no elevation changes and their flow rates are maintained at all times. List all of the possible forms of energy occurring while this reactor is operating (essentially all non-zero terms that would go into an energy balance). You should probably sketch a diagram of the reactor to find all of these forms of energy.
